It's only possible to upgrade an installation of a STS (short-term support)  
version of Ubuntu (therefore Trisquel also) to the very next version, be it  
STS or LTS (long-term support). (LTS installations can be upgraded either to  
the very next STS version or to the next LTS, launched every 2 years.)
