[Trisquel-users] Re : GNU Octave update

The commands are OK, although I would replace 'apt-get' by 'apt': a nicer  
output and less characters to type.

The risk with PPA repositories is that they can make you install proprietary  
software, or even malware, along an apparently trifling update: you have to  
trust whoever administrates the PPA.
