LXDUI config gets blown away on upgrade due to being persisted next to the source code
If you opt to install LXDUI globally (i.e. python3 setup.py install without activating a virtualenv first), configuration files such as auth.conf will be stored in and read from /usr/local/lib/python3.7/dist-packages/LXDUI-<version>-py3.7.egg/conf. This location is not the correct place to store configuration, but even worse, if the administrator runs python3 setup.py install again (e.g. to upgrade LXDUI to a new release), this configuration directory will be silently overwritten with the defaults from upstream.
LXDUI should instead read configuration from /etc - e.g. /etc/lxdui or something like that. auth.conf arguably is state instead of configuration, so maybe it should go in /var/lib (or someplace defined in lxdui.conf) but really almost anywhere is better than where it is now in /usr.

My bad, this issue was referenced to a PR that was merged and I thought that it was already introduced.
