Re: [Trisquel-users] Linterna Magica Installation

Actually if you need newer versions of software packages you must compile  
from source or add a PPA as Ubuntu does not backport newer versions of  
software packages to older releases. For example the last long term release  
of Trisquel (4.0) has an old version of Lyx which is not compatible with  
files created using the newer version. Compiling the newest version from  
source (or upgrading Trisquel) solves this problem.
