Automating Ubuntu Pro

I dont garantee these will always work, nor are they a good way of achieving some level of automation for ubuntu pro, but they worked at time of writing.

Run commands when ubuntu pro is activated

Checks if the output of the pro status command contains the string "Valid until"

# If Ubuntu Pro is Activated

LUKS Encrypted disks scripts

The following are scripts that can help with the use of LUKS encrypted disks, though they are very rudementry and require sudo.

The onlt script you will need is the crypt-format script, it's what creates the encrypted partition or file, the others just mount and unmount, which gnome can do on it's own (Other might be able to as well, but i have tested gnome)

Usage

Optional: Create mountable image

Use a GPG key for SSH authentication

These steps have been tested on MacOS. Linux should be similar if not the same. Good luck on Windows

Why would i do this?

If you are already using a GPG key to sign git commits or packages, it's one less key to securely backup.
GPG keys can be stored on OpenPGP Smart Cards like the YubiKey

Create a GPG key

Bash short hand

systemctl start service-{a,b}.service would be equivalent to systemctl start service-a.service service-b.service

systemctl start srv-{1..4}.service would be equivalent to systemctl start srv-1.service srv-2.service srv-3.service srv-4.service

If for example you had multiple wireguard services and wanted to enable both the service and path for each

systemctl enable wg{0..3}.{service,path} would be equivalent to systemctl enable wg0.service wg0.path wg1.service etc...
