Right Micha!
I now remember you posted that hint already last week.
It somehow feels hackish to create a symlink to an old grass version while
using the recommended combination of repositories [1, 2].
Nevertheless, I can confirm the hack works. I used a symlink to the available
generic grass command: sudo ln -s /usr/bin/grass /usr/bin/grass70
thanks
