Welcome to deb.mazerty.fr, my own Debian repository! This is a static website, of which you can find the contents and generating scripts here: https://codeberg.org/mazerty/deb.mazerty.fr Here is an example of how you can add this repository: # curl https://keys.openpgp.org/vks/v1/by-fingerprint/5BCA0B1E2E0E8805C141BE797ED76B9C5208D7F8 -o /usr/share/keyrings/mazerty.key # echo "deb [signed-by=/usr/share/keyrings/mazerty.key] https://deb.mazerty.fr stable main" > /etc/apt/sources.list.d/mazerty.list # apt update In a Qubes OS template, the only network access you have is through an HTTP proxy. First add these lines at the end of your .bashrc: # export HTTP_PROXY=http://127.0.0.1:8082 NO_PROXY=127.0.0.1 # export http_proxy=$HTTP_PROXY HTTPS_PROXY=$HTTP_PROXY https_proxy=$HTTP_PROXY ALL_PROXY=$HTTP_PROXY all_proxy=$HTTP_PROXY no_proxy=$NO_PROXY Then restart your bash session. Don't forget to comment the proxy lines in your .bashrc before shutting down the template.
