I am going to take the shell server, ubuntu.eskimo.com, and the web server www.eskimo.com down for maintenance tonight between 10pm-11pm to make backups prior to upgrading from Ubuntu 20.04 Focal to Ubuntu 22.04 Jammy.
After the backups I will begin upgrade. I do not anticipate long downtime for Ubuntu for the actual upgrade, only a reboot, however the webserver will take someone long as the change from OpenSSL 1.1.1 to OpenSSL 3.0.1 will require recompiling httpd.
This will affect https://friendica.eskimo.com/, https://hubzilla.eskimo.com/, and https://nextcloud.eskimo.com/ as well as all virtual domains hosted with us. I do not expect this to take more than 10-15 minutes for the actual upgrade as apache should continue to run until I reboot.
