CHIRP

I tried something like this on Debian 10 and Ubuntu:

o sudo apt install flatpak
o sudo flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

o flatpak remotes ==> 'flathub system'

o sudo flatpak update

o flatpak list --app ==> 'could be an empty list'

o sudo flatpak install ~/Downloads/chirp-daily-20201221.flatpak

N.B. the ==> is not part of the command but a cue to watch for something like that which follows.
You must make sure that you have a suitable flatpak remote hub in order to pick up the freedesktop dependency.
see the jpg attachment in issue #8571 .

Good Luck.

BY THE WAY, this is not a Chirp bug.

You should probably use the mailing list for this type of help request. There are links on how to get help (how to do this) on the Chirp home page.
