[GRASS-dev] Issues installing GRASS 7.0 from Ubuntu PPA

Thu Nov 20 08:37:25 PST 2014

Vaclav,

   Thank you for your response, it is very helpful! So, the upshot is that
the current version packaged for Ubuntu in the PPA has the broken
g.version, which somehow prevents the GUI from rendering. This is just in
the PPA version, but the compiled version *should* be fine. So my current
options are to roll back to an earlier version, compile the current version
from source, or to run GRASS headless for the moment (no issue for me)
until the problem is fixed (I assume at least by when 7.0 stable is
released?).

Also, thanks for letting me know about g.mremove. I didn't know about that!
I am currently porting some of my addon modules to 7, so I will change
their map clean up routines to use the new functionality of g.remove. Goes
to show that I ought to pay more attention to the roadmap!

~Isaac
