Re: [Trisquel-users] WARNING: The following packages cannot be authenticated!

[freeworld4]

I only have software from videolan for libdvdcss2 and from trisquel. But I  
have two packages from local. Should I remove them to get rid of the errors?  
I have the keys for videolan and of course trisquel's repo.

Should I remove videolan and install it the official way? sudo sh  
/usr/share/doc/libdvdread4/install-css.sh ?
