Good Evening Venerable Experts
Earlier on today I updated my RPi (sudu apt-get update && sudo apt-get
upgrade). On rebooting WeeWx failed to start, this was post an upgrade
from 4.2 to 4.5.1. (I have WeeWx added to the sources list)
So, being savvy, rebooted from a backup sd card to bring the system back to
where it was prior to the update/upgrade and WeeWx version 4.2.
I then went about updating/upgrading WeeWx from 4.2 to 4.5 (sudo apt-get
install weewx), that went fine, rebooted and WeeWx ran without any issues
post the upgrade.
Next I then tried sudu apt-get update && sudo apt-get upgrade again. Post
a reboot, exactly the same issue as before, WeeWx would not start:

Any ideas?
