Public bug reported:
Hello,
I just attempted to use pygit2 in Python3.4 on today's daily build of
Ubuntu 15.10. (15.04 doesn't seem to have pygit2 packaged.)
Though I am filing this bug against python-pygit2, I encountered the
issue by installing python3-pygit2, which Launchpad isn't finding.
Python 2 suffers the same issue.
Expected behavior:
I expect these two commands to exit without error when issued (after enabling
the universe packages):
sudo apt-get install python-pygit2
python -c 'import pygit2'
Actual behavior:
python-pygit2 installs fine.
Output from the Python command, triple-quoted:
"""

"""
Possible resolution:
Since it looks like a missing generated-cache file, 'sudo !!' looked like a
viable next step. A missing Python.h notice suggests the 'python-dev' package
was needed. Trying to import pygit2 again showed a complaint for a missing
git2.h, suggesting the package 'libgit2-dev' was needed. Finally, one last
"sudo python -c 'import pygit2'" creates another needed object file. pygit2 is
usable after that.
The above resolution works the same with Python 3.
>From the "-dev" packages and sudo calls needed, it looks like pygit2 as
>packaged doesn't complete all of the building necessary.
