Public bug reported:
Binary package hint: python-minimal
Version: Ubuntu 11.04
Ubuntu 11.04 comes with Python 2.7 as the default.
Because of a tool requiring Python 2.6, I installed Python 2.6 side-by-side
Python 2.7 and made it the default :)
Now, Ubuntu Software Center does not work, because it requires Python 2.7.
So, I used update-alternatives and added "python" and its derivatives
for switching between the two versions. Its terrible...
Now the real problem, the /usr/share/python/pyversions.py as well as
/usr/share/pycentral-data/pyversions.py, reads the link pointing to
/usr/bin/python to get the default python version. But after adding
python as update-alternative option, this link does not point to
/usr/bin/python2.7 or /usr/bin/python2.6. Instead points to
/etc/alternatives/python which then points to the actual python
executable.
I suppose that reading the link is not the correct way to determine the
python version. Instead, the actual python command should be executed to
get the version (that code is actually present in pyversions.py as an
exception handler).
