Software Center Flatpak Error

General Help
1

So I upgraded from Zorin 16 pro to 17 pro last week, everything works great except the software center. MVP player stopped working so I uninstalled it, but when I tried to search the software center to reinstall it I first got this error:
"Oops, something went wrong, GPG verification enabled, but no signatures found (use gpg-verify=false in remote config to disable)"

Suggestions to fix this were to run

Blockquote
flatpak remote-modify --no-gpg-verify flathub

That fixed the issue but now when I try to reinstall MVP, I get this error:
" Unable to install - flatpak remote-modify --no-gpg-verify flathub"

I can't seem to find the fix anywhere and I'm in over my head with this. Hoping one of you can lend a hand.

If you don't need the newest package of the player you can also use the Zorin package. Please first uninstall the flatpak in software center.

Then you can install it in terminal with

"sudo apt install mpv"

or in software center choose Zorin package of mpv.

Enter in terminal:

"flatpak update"

I cannot install via the software center. That is why I posted this. I'm getting errors in the software center. I'd like to resolve this issue so that I don't encounter it again with other flatpaks I may choose to install in the future.

I have already run "flatpak update" and it returned some output ending with "Nothing to do"

Hmm ... maybe something is broken. Okay, try the Following:

sudo apt reinstall flatpak gnome-software-plugin-flatpak

Then:

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

And then reboot. Don't forget that! And after reboot try it again with installing something.

Thanks the help. I ran both in terminal, then rebooted. But that dang error is still appearing in the software center when I try to install it " Can't pull from untrusted non-gpg verified remote"

When I originally tried to fix the 1st issue of the GPG verification I used this:

flatpak remote-modify --no-gpg-verify flathub

Could that be part of the problem?

You could try to go back with

"flatpak remote-modify --gpg-verify flathub"

Then enter

"flatpak update"

and restart gnome software center.

If this doesn't help you could try a solution found in this thread:

"sudo cp /var/lib/flatpak/repo/flathub.trustedkeys.gpg /var/lib/flatpak/repo/flathub.trustedkeys.gpg.bak"

"wget https://flathub.org/repo/flathub.gpg"

"sudo cp flathub.gpg /var/lib/flatpak/repo/flathub.trustedkeys.gpg"

"flatpak remote-modify --gpg-verify flathub"

Okay, so this was partly successful! It now allows MPV to install (thank you!) But now the warning is back as soon as I open the software center "GPG verification enabled, but no signatures found (use gpg-verify=false in remote config to disable)"

Also, even though MPV will install, the app won't open.

MPV worked perfectly in Z16 pro, but not with Z17 pro

That disabled the Verification of the GPG Key for Flathub which could be the Reason for:

Okay, let's try the following: Open Gnome Software and let it open. Then open System Monitor and look in the ''Process'' Tab for gnome-software and end the Process. You will see that the Gnome Software disappears; that is Intention. Open it again (that loads it new) and see if it works now.

If this shouldn't work, we will try a slightly different Way than above. First type:

sudo apt reinstall gnome-software flatpak gnome-software-plugin-flatpak

and then:

flatpak remote-add flathub https://dl.flathub.org/repo/flathub.flatpakrepo

And then reboot. Don't forget it!

Yes, perfect. That did the trick. Thanks. But I still can't get MPV to open (which is related to this flatpak issue). It worked flawlessly before I upgraded to Z17. Any clues as to how to fix that or should I start a new thread for that?

Yes, a new thread allows keeping solutions separate.
