This is Michal Goral's Debian Apt repository.

It probably doesn't have packages which you desire. It mostly has stuff which I
have created and re-packaged stuff which I use.

    sudo curl -o /usr/share/keyrings/sirlauda-archive-keyring.gpg https://packages.sirlauda.com/key.gpg

To add this repository, simply add the following entry to the
/etc/apt/sources.list.d/sirlauda.list:

    distro=$(lsb_release -cs) && \
        echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/sirlauda-archive-keyring.gpg] https://packages.sirlauda.com $distro main' | sudo tee /etc/apt/sources.list.d/sirlauda.list
