Mnemosyne won't start

Asked by Joscha Finger

The problem started while I was still using the 12.04 release, but it hasn't changed with yesterday's upgrade to Ubuntu 12.10. When trying to start the program from the Launcher, it looks as if it was loading, but nothing happens, not even an error message.

 Upon typing "Mnemosyne" in the Terminal, I get the following reply:

Traceback (most recent call last):
  File "/usr/local/bin/mnemosyne", line 4, in <module>
    import pkg_resources
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2819, in <module>
    parse_requirements(__requires__), Environment()
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 588, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: Mnemosyne==2.1

, the meaning of which simply escapes me. I've tried uninstall-reinstall via Software Center, but there is no change.

What can I do?

Regards,

Joscha

 Right, I've managed to solve it myself. Apparently a failed attempt at updating left rests all over the place -they could be found by simply searching for "Mnemosyne".

 I deleted all those files manually using "sudo rm [path/filename]" for each of the files. Then, I simply reinstalled using the Software Centre.

 Mnemosyne works perfectly now.
