I notice that when installing the new public version of SNAP 7, I face the problem of SNAP being locked to root. It means that “clicking” on the SNAP icon, you’ll get a error message describing that you are not allowed to access data inside .snap
The strange thing is that I never had that on previous installation of SNAP.
Whatever, the solution for users facing the same issues is simply to go on your installation folder (for me it’s “/home/qg”), open a terminal, and type
sudo chmod 777 .snap
