Bug description:
[ Impact ]
When apt cannot be run as a normal user, and a pro command is run as a
normal user, a bug occurs in the error handling. An UnboundLocalError
occurs.
The fix is to give that variable an initial value so that it is not
unbound during the error handling.
[ Test Plan ]
lxc launch ubuntu-daily:jammy test
lxc shell test
# now inside the container
# intentionally mess up permissions on apt-related files
chmod 600 /var/lib/dpkg
sudo -u ubuntu pro version
# that will give you a long backtrace if the bug is present
[ Where problems could occur ]
The changed code involves notifying the user if there is a newer
version of u-a-t available. It runs at the end of every pro CLI
command. If a mistake was made it could prevent pro from notifying
users that an update is available. In the worst case, if the change
causes a permanent error, then that would cause all pro commands to
start exiting non-zero.
