[Trisquel-users] Re : Qt5 on Trisquel 5.5

[magicbanana]

You probably do not want to do that. Many applications depend on Qt. A  
distribution is a coherent set of applications and libraries. If you update  
Qt, many other applications in the repository would not work (or even be  
installable). Observe that Qt5 is not even included in Debian unstable (also  
known as sid, the name of the kid breaking toys in Toy Story).

The good reason to install Qt5 today is to develop software using it. I doubt  
it is what you want to do since you talk about replacing Qt4 with Qt5.
