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

For directly installing Debian Sid not supported by the Debian installer, namely:

• Single LUKS2 encrypted partition which contains the full installation
• Single BTRFS filesystem (integrated home partition)
• Encrypted swapfile in BTRFS subvolume (supports laptop suspend but not hibernate)
• Uses systemd-boot bootloader (instead of Grub2, also optional rEFInd instructions)
• Minimal Gnome install (plus instructions for any other DE you wish)
• Proper user groups for common security tools like sudo-less Wireshark, etc...
• Optional removal of crypto keys from RAM during laptop suspend
• Optional configurations for laptops (including fingerprint readers)

Assigning Static IP Addresses in WSL2

WSL2 uses Hyper-V for networking. The WSL2 network settings are ephemeral and configured on demand when any WSL2 instance is first started in a Windows session. The configuration is reset on each Windows restart and the IP addresses change each time. The Windows host creates a hidden switch named "WSL" and a network adapter named "WSL" (appears as "vEthernet (WSL)" in the "Network Connections" panel). The Ubuntu instance creates a corresponding network interface named "eth0".

Assigning static IP addresses to the network interfaces on the Windows host or the WSL2 Ubuntu instance enables support for the following scenarios:
