you are not doing anything wrong. AFAICT the tarball was created
containing permissions and ownership info which it should not have.

as Micha mentioned, something like this should fix it:
  chown -R anrr.anrr /home/anrr/Desktop/gisdata

which makes your user the owner of all those files.

that is not good practice. avoid it if you possibly can.

as long as you own the mapset your user is trying to open, there should be no problem for you running grass yourself.


if there is not mention about mapset ownership rules in the FAQ
and first-day introduction documentation please let us know so
we can fix that.
