Re: [Trisquel-users] Not getting the ability to upgrade

janitor does more than that -- to me, it offers to remove any package which  
is not on the repos I use, like libdvdcss2 which I installed by running  
/usr/share/doc/libdvdread4/install-css.sh --; you should be safe using only  
"autoremove" and "clean".

To know which linux-* packages are installed you could type "apt-get remove  
linux" in a command line and hit TAB two times -- the terminal would show you  
which packages beginning with "linux" you can remove.
