Tutorial datasets---how to start?

[Alan Eugene Davis]

Long ago, I installed the spearfish tutorial data  set.  Now I have
upgraded to 4.2.1, this data set is working.  I haven't been able to use
the imagery or global data sets.  When I try to specifiy anything, in
the opening screen (asking for mapset etc.) I always get the message
that I do not have permission to access the mapset.

I changed the ownership and permissions, without success.

I have not been able to find a tutorial that explains this aspect of
grass use.  Is there something out there?
