[Bug 2038900] [NEW] setting XDG RUNTIME to not 'tty' and SUDO_UID and PKEXEC_UID being unset causes TypeError traceback

[Tim Andersson]

Public bug reported:

Running do-release-upgrade in an environment with XDG_RUNTIME set to
something other than tty, and also in an environment where SUDO_UID and
PKEXEC_UID are unset (e.g. ssh'd straight into a root session, no sudo)
causes a TypeError traceback in the upgrade logs.

Reproducer:
lxc launch images:ubuntu/lunar --vm
lxc exec vmname bash
apt update
apt upgrade
export XDG_RUNTIME=unspecified
do-release-upgrade -d -f -f DistUpgradeViewNonInteractive

None will eventually be printed, then you can go to the upgrade log and
find the traceback.
