    OpenPGP SSH access with Yubikey and GnuPG
Yubikey, Smart Cards, OpenSC and GnuPG are pain in the ass to get working. Those snippets here sould help alleviate pain.
Notes written here should work on

Ubuntu 20.04 with Gnome
Debian 11 with Gnome
Linux Mint with Cinnamon (needs different environment setup, check comments)
Arch Linux with Gnome (pacman instead of apt)

This is not a step by step guide

                How effectively delete a git submodule.

    To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule
