[Bug 1655497] Re: package python-cryptography 1.2.3-1 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1

[Robie Basak]

Thank you for your report.

This looks like a local configuration problem, rather than a bug in
Ubuntu. Specifically, it looks like you have replaced the
/usr/bin/python symlink with Python 3 and thus broken the system.

You can find pointers to get help for this sort of problem here:
http://www.ubuntu.com/support/community

Since we use this bug tracker to track bugs in Ubuntu, rather than
configuration problems, I'm marking this bug as Invalid. This helps us
to focus on fixing bugs in Ubuntu.

If you believe that this is really a bug, then you may find it helpful
to read "How to report bugs effectively"
http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful
if you would then provide a more complete description of the problem,
explain why you believe this is a bug in Ubuntu rather than a problem
specific to your system, and then change the bug status back to New.

** Changed in: python-cryptography (Ubuntu)
       Status: New => Invalid
