New Year New Fear
I thought I’d update this VPS from Ubuntu 20.04.5 LTS to Ubuntu 22.04.1 LTS. I ran
do-release-upgrade which gave all the appropriate warnings and stuff, and proceeded to upgrade. This VPS is hosted on Linode, so there’s a local Ubuntu mirror — the download is blindingly fast.
do-release-upgrade process appears to run in a Unix screen window. Unfortunately, that interacted poorly with the terminal I was using, so any time I moved my mouse, it spewed control characters as input. That was bad when it was prompting … something? … probably about my nonstandard sshd configuration.
Anyway, Linode provides a web-based console access, so I was eventually able to fix the broken sshd, PHP, and Apache configurations. Only about two hours of downtime. Not bad for New Year’s Day.
And today, upgraded to Ubuntu 22.10 without issues.
