Preference block lists for the Apt package manager, for Debian 11 or newer.
If you use block-browsers.pref, it helps if you want to install a newer version of your favorite browser from Flathub or something similar.
However block-thunar.pref and block-xfce4.pref may cause issues.
To install this project, use:
git clone https://github.com/aleksiaksu/aptprefs.git ~/aptprefs
cd ~/aptprefs/debian
sudo cp *.pref /etc/apt/preferences.d
