I started a new conversation to address issues from several other threads.
I am using UBUNTU 24.04. Upgrading weewx from 5.0.0b10 to 5.0.1.3
After spending hours diagnosing issues similar to those mentioned in the other threads here, this is what I did to resolve the issues -
Backup anything important before you do anything (weewx.conf. etc.)
It is especially important to make a backup copy of the
/etc/weew/skins/ folder as this apparently get
doesn't reinstalled
Using Synaptic, I completely removed weewx (INCLUDING ALL CONFIGURATION FILES).
I reinstalled weewx.
After restarting weewx there were multiple permission issues in /home/(user_id)/www/ and /etc/weewx/
Note that files that used to be in /usr/share/weewx/user/ are now in /etc/weewx/bin/user/
