I’ve had a few issues with the discover store only working sporadicly in desktop mode amd when looking it up found ne good solutions that don’t require a system restart or work reliably.
The error I had was something along the lines of a lost connection due to a refused TSL-Handshake these are the errors I get trying to refresh the available updates for example:
I press update All and get:
no metadata URIs for vendor-directory
I press it again:
the application […]/x86_64/stable requires the runtime org.kde.Platform/x86_64/6.4 which was not found
and again:
aborted due to failure (While pulling runtime/org.kde.Platform.Locale/x86_64/6.4 from remote flathub: Peer failed to perform TLS handshake: Error recieving data: Connection reset by peer)
I would love it if anyone can help me with this as I would like to be able to reliably update my packages (and install new ones which often jeilds the same errors)
I have tried installing over the terminal, which results in the same errors. I have tried it on different Networks. I have restartes flatpak-sytem-helper. service as well as wpa_suppclient.service I have tried flatpack repair. Restarts of the whole system work occasionally but not reliably.
Correction I guess update didn’t change the build number… thanks steam for making sense. The bottom half of what I wrote should still help. I’d try switching to prieview (or stable assuming you’re on beta) and forcing an is update that way then switching back to what you want. SteamOS has gotten a lot better since day 1 but for the occasional issue this has almost always seemed to work for me
