I just switched back to the Ubuntu 21.04 VM and collected lots of evidence
of mosquitto not starting properly.
These are the commands that Vince requested:
weewx@Ubuntu20-WEEWX:/run$ ls -lagd /run/mosquitto
drwxr----- 2 mosquitto 40 Jan 1 11:37 /run/mosquitto
weewx@Ubuntu20-WEEWX:/run$ ls -lagd /run/mosquitto/*
ls: cannot access '/run/mosquitto/*': Permission denied
weewx@Ubuntu20-WEEWX:/run$ sudo rm -r /run/mosquitto
weewx@Ubuntu20-WEEWX:/run$ sudo systemctl start mosquitto
Job for mosquitto.service failed because the control process exited with
error code.
See "systemctl status mosquitto.service" and "journalctl -xe" for details.
