@variablepulserate "if it ain't broke…"
I tend to suffer from update fatigue. I'll do it in fits and starts. I only recently went from Ubuntu 16 to 20 (or whatever is the latest LTS. 24?) and had to create a whole new droplet in DigitalOcean because it wouldn't allow a direct upgrade.
Was forced to do it to get some new PHP features, otherwise I'd have avoided it for years!
