Bug Description

I have Ubuntu 9.10 32-bit and Python 2.6. I've installed the software with (sudo python install) and everything was fine. But if I try to run it it outputs the following error:

marius@marius-desktop:~/Desktop$ gpoweroff
Traceback (most recent call last):
  File "/usr/local/bin/gpoweroff", line 221, in <module>
    window = NewGpoweroffWindow()
  File "/usr/local/bin/gpoweroff", line 197, in NewGpoweroffWindow
    ui_filename = os.path.join(getdatapath(), 'ui', 'GpoweroffWindow.ui')
  File "/usr/local/lib/python2.6/dist-packages/gpoweroff/", line 50, in getdatapath
    raise project_path_not_found

Any ideas? Thanks!

Hi Marius,

That looks rather serious :-). Can you please tell me the location of 'AboutGpoweroffDialog.ui'? From a command line you could find it by doing either:
locate AboutGpoweroffDialog.ui
# or
find / -name AboutGpoweroffDialog.ui -print

On my system it lives in /usr/share/gpoweroff/ui . It looks like you have everything stored under /usr/local, which I suspect may be throwing the script. Out of interest, what distro are you running?

Thanks for your feedback on this too by the way :)... it is much appreciated

Hope this helps, 'cause I really want this tool... as GShutdown doesn't work!

Ahh. I suspect I know the issue. Can you paste the output of:

grep __gpoweroff_data_directory__ /usr/local/lib/python2.6/dist-packages/gpoweroff/

It looks like the does not correctly re-write the actual data dir, and assumes the data dir is in the wrong location.

If you want, there is a deb file available from my ppa at that I am far more confident works (i.e., I actually use it :) ). I'm planning to put up a team repository for GPoweroff soon so that Ubuntu users can easily stay up-to-date.

Ok... official builds are now available from Are you able to install that and try again?

One last query Marius, did you specify a prefix when installing gpoweroff? I've just done an install in a VM and by default it installs to /usr/bin/gpower, rather than /usr/local/bin/gpoweroff as your error shows the location to be. This is what is causing the issue you're experiencing.

Changed in gpoweroff:
importance: High → Wishlist
status: In Progress → Confirmed

I've installed the DEB file on my home PC (Ubuntu 9.10 AMD64) and it works very well now!

Thank you and keep up the very good work!
