Caveat that this only applies to USB chargers. If you find some random non-USB, old-school type charger (like the ones with the round connectors) that fits your device, don’t plug it in until you’re sure that the voltage and polarity are correct.

Interesting, thanks. Maybe it’s something with the entire Ubuntu branch.

That’s odd. Maybe it’s a limitation with Ubuntu or their downstream distros. I’m now positive that all 3 of those distros I listed gave me the option to encrypt the disk during installation. This was in the last 3 months or so.

In my recent experience, I’m pretty sure all distros I tried (Debian, Bazzite, openSUSE) had a simple checkbox to do full disk encryption.
