An update appears to have messed up my system preventing me from even accessing the web pages; something about GPG keys stored in redis. My attempts to correct this appears to have made things much worse. So time for a complete reinstall.
The only thing that I need to save from the old host is my licenses, and those appear to be in /etc/schmooze
I’m assuming that I can archive /etc/schmooze, rebuild the system, put /etc/schmooze back in place, and reboot. Is this correct? Is there anything that I’m missing?
