Problem installing Flacon

I have a fresh install of Q4. I have tried installing Flacon from the Discovery centre, and I've also followed CLI guides, but the install fails.

The Discovery route just hangs and never completes.

The CLI routes fail with a missing/incorrect key.

Has anyone found a reliable method?

Look for Falkon in Q4OS Software Centre.

Re: Problem installing Flacon

Thanks, but this is a different application. I am trying to install Flacon, which can break a long flac/cue file into individual tracks.

Please run in terminal and post back the output:
$ sudo flatpak install com.github.Flacon

SOLVED

I tried adding the flatpak in Discovery, but it just hung.
I tried sudo apt install flacon, but it couldn't get past operation 1/8.

Then I tried your suggestion of installing from github and it worked - output below:

Installation complete.

I'm very grateful for your help - there is no other app that can easily replace flacon for my uses.
