Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

From log:

  File "/usr/bin/pyclean", line 63
    except (IOError, OSError), e:
                             ^
SyntaxError: invalid syntax

This is generally reported when you have changed your default python interpretor from Python 2 to Python 3 or some other version. You really should not change this as it will lead to unexpected behavior like what you have observed.

I am marking this "Invalid", however if you have additional details about the issue please feel free to add them here and mark this as "New" to be looked at again.
