Ubuntu desktop 24.04 Annoyances

This is a collection of annoyances that I have had to fix for myself while using the Ubuntu 24.04 desktop. Snaps are obviously the most annoying thing that Ubuntu does. Especially for Firefox. If you need to use smart cards or other tools with Firefox you may consider removing the snap version. I don't know the steps to completely remove snapd from a desktop system and retain all the functionality provided by those snap applications. I update this doc when I can remember.

Set vim as default editor

The Ubuntu install defaults to some weird text editor called nano. I have no idea how it works. I think it is new. You can change the default text editor.

sudo update-alternatives --config editor

You may need to install a more complete vim editor instead of the tiny vim that is installed by default.

Ubuntu 24.04 Firefox snap replacement

I need a proper Firefox installation and not the snap version. The snap version does not work properly with Smart Cards. Although it seems to be possible to get it to work with smart cards it is extremely difficult and I don't care to try and make it work. Also snaps suck. Canonical will heopfully abandon snaps in the future.

Remove Snap Firefox

sudo snap disable firefox
sudo snap remove --purge firefox
error: cannot perform the following tasks:
- Remove data for snap "firefox" (1943) (unlinkat /var/snap/firefox/common/host-hunspell/en_ZA.dic: read-only file system)

Bluey Season 2

Fixing Bluey Season 2 to conform to the TVDB order. This fixes the giant mess displayed in Plex. Otherwise titles, descriptions. and other metadata will not match to the correct file.

Reorder

Move the incorrect episode number to the correct episode number temporarily. This avoids overwriting needed files.

mv -v Bluey\ \(2018\).S02E01.Dance\ Mode.WEBDL-1080p.h264.EAC3.mkv Bluey\ \(2018\).S02E02.Hammerbarn.WEBDL-1080p.h264.EAC3.mkv-tmp

Ubuntu 22.04 Annoyances

Here are a few collected ways I like to customize Ubuntu 22.04 servers. I used to love Ubuntu, but I hate auto updates and snaps. They also put ads and other usless ads diguised as "news" in MOTD. ESM FUD is spread throughout the OS including simple apt functions. You do not need ESM and thus Ubuntu 22.04 has become super annoying. unattended-upgrade is an automatic installation of security (and other) upgrades without user intervention. Consider the ramifications of disabling this service.

Disable unattended upgrades

The Unattended Upgrades feature is enabled by default and it runs at system boot without the user's permission. The configuration is stored in /etc/apt/apt.conf.d/20auto-upgrades

Disable: sudo dpkg-reconfigure unattended-upgrades then a TUI will come up, select "No"

This will not permantently disable the function. After an update it will be enabled. In the file /etc/apt/apt.conf.d/20auto-upgrades change these values from 1 to 0. Even doing this it will

TCP tuning

The most important TCP tuning areas since kernel 4.9 are:

packet pacing
dynamic TSO sizing
TCP small queues
BBR TCP congestion algorithm
