Ubuntu 22.04 Annoyances

Here are a few collected way I like to customize Ubuntu 22.04 servers. I used to love Ubuntu, but I hate auto updates and snaps. ESM FUD is spread throughout the OS including apt. 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

sudo dpkg-reconfigure unattended-upgrades
sudo apt remove unattended-upgrades

Disable apt news

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

Definitions

• Gb = gigabit
