Innovative New Linux Desktops and other Changes in Fedora 30

Fedora 30 was released on April 30. The Fedora Wiki contains a complete list of the changes that were accepted for inclusion in this release. These changes include two new desktop environments, other new features, and bug fixes. Some older packages have been deprecated or completely removed.

As you can see in my previous post, I have already upgraded all of my physical hosts and I have created a new VM for Fedora 30. All of these hosts are working very well and I have not had any problems so far.

Fedora 30 and my books

Fedora 30 should make no difference in any of the experiments in my book, The Linux Philosophy for SysAdmins, Apress, 2018. That book was written using Fedora 28 but everything should also work just fine with Fedora 29 and 30.

I am also working on two new books, the titles of which I cannot yet divulge. The experiments in these two books are being tested to ensure that they work on Fedora 29 and 30. These books should be available late this year but I will keep you informed with future posts here on this site.

The changes

I have listed some of what I consider the more interesting changes along with a short description of each. Much of this information is distilled directly from the Wiki page but I have not included all of the changes listed on that wiki page.

New desktop environments


Add the Deepin Desktop Environment. Deepin is a Chinese Linux distribution and DeepinDE is its desktop. The DeepinDE is based on the Qt 5 toolkit so can be easily installed on other distributions. It is intended to be simple and easy for new users.

Pantheon Desktop

Another new desktop for Fedora, the Pantheon desktop environment is the minimalist Desktop Environment that powers elementaryOS. It builds on GNOME technologies, but utilizes components that were written from scratch in vala, using the GTK+3 toolkit.

Other changes

Bash 5.0

Upgrade bash to 5.0 release. This release fixes several outstanding bugs in bash-4.4 and introduces several new features. The new features include some new Bash environment variables and improved history command that can delete ranges of history.

Boot Loader

Make BootLoaderSpec-style configuration files the default. This change enables the use of per-boot-entry configuration files, similar to those described in Boot Loader Specification (BLS), to populate the bootloader’s menu entries.


Make dbus-broker the default DBus implementation. Enable dbus-broker.service to use dbus-broker as system and session message bus backend. DBUS provides communications that allow things like plug and play to work by distributing event notifications to applications and kernel level tools.

Boost 1.69 upgrade

This change brings Boost 1.69 to Fedora. Boost is a set of free, peer-reviewed, portable C++ source libraries This will mean Fedora ships with a recent upstream Boost release.

Flicker Free Boot

Make Fedora Workstation boot graphically smooth, without the display briefly turning off and without any abrupt graphical transitions.

FreeIPA Python 2 Removal

No it is not free beer! FreeIPA 4.8 will require Python 3.6+ and therefore no longer provide Python 2 packages on Fedora 30.


Fully remove deprecated and unsafe functions from libcrypt. This change is about removing binary support for deprecated and unsafe functions and bumping to


Switch GCC in Fedora 30 to 9.x.y. An attempt will be made to rebuild all packages with it, or optionally rebuild just some packages with it and rebuild everything else in Fedora 31.

GNU C Library

Switch glibc in Fedora 30 to glibc version 2.29.

GNOME 3.32

Update GNOME to the latest upstream release, 3.32.

GnuPG 2

Use GnuPG2 as the default GPG implementation. The /usr/bin/gpg path representing the main GPG implementation will now use GnuPG 2 instead of GnuPG 1.

Mass Python 2 Package

(Sub-)packages only providing python2 importable modules without additional functionality will be removed from Fedora unless some other package(s) depends on them.

Obsolete Scriptlets

Remove scriptlets which are not needed anymore (ldconfig, gtk-update-icon-cache, etc.).

Locale settings

When logging in over ssh or another mechanism, locale settings are forwarded. If the destination does not support that locale, C.UTF-8 will be used instead.

Ruby 2.6

Ruby 2.6 is the latest stable version of Ruby. Many new features and improvements are included for the increasingly diverse and expanding demands for Ruby. With this major update from Ruby 2.5 in Fedora 29 to Ruby 2.6 in Fedora 30, Fedora becom

Deprecate /etc/sysconfig/nfs

Deprecate /etc/sysconfig/nfs and only use /etc/nfs.conf to configure NFS daemons.

uEFI for ARMv7

Move to uEFI as the default boot mechanism for ARMv7 devices.

Fish 3.0

Update Fish to 3.0. Fish allows tools like Midnight Commander and other file managers to access filesystems on remote hosts for easy copy and move from one host to another.

Haskell GHC 8.4 and Stackage LTS 12

Update the ghc Haskell compiler version from 8.2.2 to 8.4.4 and Haskell packages to Stackage LTS 12 versions.

LXQt 0.14.0

Update LXQt to 0.14.0.

MongoDB Removal

The Server Side Public Licensev1 (SSPL) under which MongoDB is distributed is not a Free Software License. Therefore, MongoDB has been removed.

java-openjdk JDK12

Update rolling package of java-openjdk to JDK12

krb5 crypto modernization

krb5 will be removing support for DES, 3DES, crc-32, and MD4 entirely; they will not be allowed in session keys or long-term keys. Additionally, RC4 and MD5 will be marked deprecated and dangerous.

PHP 7.3

Update the PHP stack to latest version 7.3.x

Upgrading to Fedora 30

Yesterday, April 30, Fedora 30 became available. Fedora 30 has some interesting new features as well as some bug fixes so I decided that I wanted to upgrade all of my physical computers as soon as possible.

I first upgraded one of my test computers from Fedora 29 to Fedora 30 just to verify that the upgrade would work. This host worked just fine after the update so I began the process of upgrading the rest of my hosts. All of my hosts have been successfully upgraded to Fedora 30.

Because multiple steps are required to perform these upgrades, I have a script that I use, called It automatically performs all of the steps required for upgrading from one release of Fedora to the next. The guts of the code are shown below.

 # Set the new Fedora release number
# Do all current updates to prepare for the upgrade
dnf -y update --refresh
# Install the system upgrade plugin
dnf install -y dnf-plugin-system-upgrade
# Perform the upgrade
dnf -y system-upgrade download --refresh --releasever=$TargetRelease --allowerasing
# Reboot and perform the upgrade
dnf system-upgrade reboot

You can use this little script as it is, but I have a more easily used script that handles things like obtaining the value of the variable $TargetRelease from a command line option. You can download the complete script from to get the complete script.

I did have one problem on one of my servers. The /var filesystem filled up during the download of Fedora 29 packages and it generated an error to that effect and exited. I used LVM to extend the /var logical volume, expanded the filesystem itself using resize2fs, and reran the script. The upgrade programs called by the script know enough to pick up where they left off, doing nothing for any step that is already completed. A reboot was not required because Linux LVM allows this to all be done with the filesystem on-line and active.

Fedora 30 has both graphical and command line options for performing upgrades. See this Fedora Magazine article for details of both methods. I personally prefer the command line methode so I can do these upgrades remotely on several computers.

Linux process scheduling

I read an informative and interesting article today at about process scheduling in Linux, CFS: Completely fair process scheduling in Linux. It goes into some detail about the Linux Completely Fair Scheduler which has been around now for a bit over a decade.

Understanding how the Linux kernel schedules tasks for CPU time is an important part of our knowledge as SysAdmins. It enables us to understand why programs might be unresponsive and how to deal with that. Dr. Marty Kalin, the author, has covered this in an understandable way that helped me to understand this important kernel task.

Don’t miss this excellent article.

Server repairs completed

It has been a challenging few days due to a series of hardware failures. I had two systems that were complete failures two with minor problems and one that might be easily fixable. But the server is back up and running so email and my web site are functional again.

It all started last week when my old server crashed due to an intermittently failing hard drive. I managed to get that back up and running temporarily with a bit of luck and a complete BIOS reset. I was able to keep it running long enough to choose a spare host and move DHCP, DNS, NTP, and firewall services to it.

While I was working to move additional services to my new server, the motherboard on my wife’s computer failed so I took some time to replace that. Of course the motherboard on that system was so old that the only option was to go with a new motherboard, CPU, memory, and a power supply that could deal with an Intel i7 1151 hexa-core processor.

After fixing my wife’s system and getting a good bit of work done to move web services and email to my new server, the old one died permanently.

It took me a couple days to get web and email up and running on the new server because I was moving from CentOS 6 to Fedora 29 which included updates to both Sendmail and Apache. It took a bit of research but I was able to determine that the fix for each were minor changes to obscure configurations for the newer versions of those services.

Both web and email are complex installations. My web site uses Apache web server and WordPress with a MySQL (MariaDB) back-end database. For email I use Sendmail with SpamAssassin and MimeDefang for spam filtering. The good news is that a simple restore from backups of the data and everything was up and running – you do make backups, don’t you?

I apologize if you tried to send me email or visit one of my web sites and were unable to get through. If you send me email between January 21 and today and did not receive an expected reply, please let me know and I will respond as soon as possible.


Server upgrade in the works

After some work to determine the extent of my server problems, I have decided that it is time to go for a complete upgrade. I have another Fedora Linux system that I have been using for several months that is the prime candidate as the target for this move.

Over the next few days I will be moving services such as DHCP and DNS from the old server to the new. After the basic service moves, I will move web and email services to the new server.

I intend to go slowly and ensure that each service is working properly on the new server before working on the next.

There will be outages of various lengths during this process although I am hoping that only one service at a time will be affected. Where possible I will try to post a notification here in advance of outages. I may not be able to do that in all cases but I will try.

Again, thanks for your patience.

Web Site Outages Today

Due to a failing power supply, my web and email host has been repeatedly rebooting every few minutes this morning. This caused intermittent web site outages and would have made accessing this web site quite frustrating. I apologize for the inconvenience.

I was able to determine that it was the power supply quite easily because it was very hot to the touch. After replacing the power supply the server is now running butu there is still a problem.

There appears to be an issue with the motherboard in which the system dies and won’t restart when the case is placed in an upright position. This is probably cause by a short on the motherboard that is created when the case is upright and the weight of the cables is causing different force vectors on the main board.

I hope to do some additional testing to determine the true source of the problem and repair it. This might require purchase and installation of a new motherboard.

Expect more hopefully short outages today and possibly tomorrow as well.

Thanks for your patience.

Why I Hate Windoze

Well – one reason anyway.

I use a virtual Machine (VM) with Windows 10 installed for research on a new book I am writing. I started that VM this afternoon to do some testing and took a few screen shots to include in that book. After I finished up with that, I was going to shut down the VM but then this – the Blue Screen of Updates.

Windoze Blue Screen of Updates

This has been going on for hours, now, despite the fact that this VM has assigned to it 8 CPUs (4 Cores) of the 32 CPUs (16 cores) and about 24GB of RAM of the 64GB that I have on the physical host. Here is what that looks like in htop.

These lines copied from htop show that the Win10 VM has been running for hours and taking over 26GB of RAM. This includes what I assigned plus the VirtualBox overhead. But that is huge in terms of both RAM and CPU time. Updates to a Linux system never, ever take that much system resource or real-world time. 

Meanwhile, the virtual machine is of no use to me as I cannot do anything on it until the updates and multiple reboots are completed. Not to mention the fact that I had no choice about when this happened. It just started and did not give me an opportunity to opt-out.

On Linux I can work while the updates are being installed, and I do not have to reboot until I am ready. Only one reboot is ever needed to install updates and I can choose when I want the updates to be installed and then, separately, when I want to reboot my Linux computer.

To make this even more disturbing, after it finally rebooted for the umptieth time — or so I thought — I logged in and it had the audacity to display in the screen, “Hi. We have some updates to install,” or something to that effect. 

Some of my friends wonder why I don’t use Windows. This is one reason. 

Fun with ASCII art on the Linux command line

This really brings back memories of when I worked night shift on an IBM 1401 and we used to print ASCII art on the IBM 1403 printer when we had nothing else to do.

This fun little utility, boxes, can draw various forms of boxes around text at the Linux command line. Jason Baker, my friend at found this and made it the subject of the first of 24 articles he will be publishing this month.

                 (__/ \__)

I look forward to Jason’s next Linux toy.

About The Linux Philosophy for SysAdmins

The Linux Philosophy for System Administrators is not about learning new commands, processes, or procedures. Rather it is about becoming a better SysAdmin through understanding the power of Linux as a function of the philosophies that built it. SysAdmins will learn how to unleash that power with the knowledge enabled by a philosophical approach that targets their unique needs.

This book uses a relatively few common Linux commands to illustrate practical, usable aspects of the philosophy. Readers will learn a philosophical approach to system administration that will unlock the power of the knowledge they already have. This book will enable SysAdmins and others to more fully understand and access the vast power of the command line using commands and tools that they already know and use.

This book takes place on the Linux command line, but it is not about the commands themselves. The commands are only the tools through which the beauty of the underlying structure of Linux is revealed. This book will help you learn how to do that using the philosophy contained in its pages.

Book availability update

My book The Linux Philosophy for SysAdmins is now available in hardcopy (softcover) at Amazon.

Please note that for a couple days Amazon was fulfilling this via a third party storefront on Amazon. Amazon now has my book in stock and it is currently sold and fulfilled directly through Amazon.

I would appreciate any reviews you post on Amazon, good or bad. I am writing two new books and any feedback will be appreciated so that my next books can be even better. If you wish to contact me directly, please do so.

Meet the author(s) at ATO

On Monday, October 22, from 12:45 PM – 1:15 PM, my publisher, Apress, will hold a “meet the authors” session at All Things Open in Raleigh, NC. Several authors of popular Apress books, including myself, will be available for questions and discussion. We will also be happy to sign books for you.

Authors present at this session will be:

  • Mary Thengvall
  • Azat Mardan
  • Preston So
  • David Both
  • Gordon Haff
  • Waldemar Quevedo

We look forward to meeting you.

My Ohio LinuxFest presentation

I am scheduled to present my talk, “Be the Lazy SysAdmin,” at the Ohio LinuxFest Saturday, October 13 (tomorrow as I write this) at 10AM in the Franklin A room. Due to circumstances beyond my control I am unable to be there in Columbus at OLF.

However, my presentation will still take place. I have arranged to present my talk remotely from my home in Raleigh, NC. This morning we tested our remote solution, right from Franklin A, and everything seems to be working perfectly. Of course things never work perfectly on the day of, so please bear with us if we run into any snags.

I am experiencing much angst at not being able to be there in person because I am unable to interact with you all as freely as I would like. We will have Scott Merrill in the room to help by passing questions to me and letting me know when you look bored or perplexed. ;-)

I hope you will understand my distress at not being there to meet with you face to face. I promise to do my best to make this the session you were expecting.

Thank you!

Yet another book contract

I have just signed with Apress for third book about Linux. With two books now in the pipeline it looks like I will be busy for a while. I do not have definitive dates when these books will be on the shelf but my schedule calls for the writing to be completed by Summer of 2019 for the first and Autumn of 2019 for the second. These books constitute a two-book series.

As soon as I can post more information I will.

New book in the works

This morning I signed a contract to write another book for Apress. This book will also be about Linux but it will be different from my first book, The Linux Philosophy for SysAdmins. I cannot divulge more about it at this time, but I am very excited about writing another book for Apress. I will post more information as soon as I am able.
