Hi Battery and welcome to the forums!
To install PeerGuardian (later just pglgui) on Trisquel GNU/Linux, open a new
Terminal window (by pressing [Ctrl]+[Alt]+[T]), and type:
sudo add-apt-repository ppa:jre-phoenix
sudo apt-get update
sudo apt-get install pglgui
To add pglgui to the list of Startup Applications (e.g. those that will
automatically start after you log in), also type the following:
ln -s /usr/share/applications/pglgui.desktop ~/.config/autostart
After you have successfully installed pglgui, you also need to whitelist some
of the connections. By default, PeerGuardian filters nearly all of your
connections, and software like Update Manager, Weather applets, Tor network,
will refuse to work. To make it simple for you, here is a picture of my
pglgui configuration:
Bear in mind that even after all of this, you can easily experience torrents
or files from one-click hosting websites refusing to download. If this
happens to you (like it happened to me), try to temporarily stop the
PeerGuardian Daemon by right-clicking on the pglgui panel icon, and selecting
Stop as seen on the following picture:
Good luck!
