On Lucid, by default (at least, using bin/ivle-dev-setup), the /etc/ivle.conf will be created with 'lucid' as the Ubuntu version inside the jail. Running ivle-buildjail -r results in this error:
Package python2.5 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package python2.5 has no installation candidate

This is because buildjail specifically depends on python2.5, but that package has been removed in Lucid in favour of python2.6.
Not sure how to fix this and remain backwards-compatible, but this is going to keep happening, so we need a better solution. If buildjail were to depend on the same version of Python that is installed on the host machine, what problems would that cause? If buildjail *does* get the correct version of Python installed, are there any other issues? (Looks like it's working fine with me, by just modifying buildjail to use python2.6).
Workarounds:
- Change /etc/ivle.conf - jail/suite to karmic manually before running ivle-buildjail -r.
- In ivle-buildjail, manually s/python2.5/python2.6/g.
I managed to get a fresh build of IVLE running in Lucid (with a Lucid jail) just by modifying ivle-buildjail to use python2.6 instead of python2.5. So the fix for this should be to make ivle-buildjail somehow smart enough to figure out which version of Python to install.
But I don't think using sys.version is correct -- that will set the jail version to whichever version is running outside the jail, which isn't necessarily correct.
