Using Signal on PinePhone in mid-2023?

[zetabeta]

I use Signal-Desktop from here. When I first installed it on my PP I used my old Android phone to link Signal on the PP.

But since I don't use Android anymore I'm now using the signal-cli to link Signal-Desktop on my computer and PPP (see Installation, Usage - Register a number, Linking other devices - Add another device).

Tried today, it worked! 
Cool that something like signal-cli exists.
Again: Thank you!

Another short question: How about later updates? Do you just download and install the package of the new version? Or are further steps necessary then (register again or something like that)?

signal-cli stores keys and other userdata into "~/.local/share/signal-cli/". so i assume just running new version and that's it. (assuming that newer version does not use userdata differently).

not tested though, i think i can transfer those registration keys to another signal-cli by just moving above mentioned directory.
