Extension Manager crashes - Error pops up

System Information:
Could not check for updates: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Object does not exist at path “/org/gnome/Shell/Extensions”

Which distribution are you using? It looks like you may be missing a dependency like gjs or similar.

[m0070]

Fedora 41 - Gnome 47

[oscfdezdz]

#320 and #391 are related, although Fedora should have all the required dependencies installed out of the box. Could you check, if you haven't already, that you have gjs installed? If it is, official Extensions app, either installed from Flatpak or via dnf may have the same issue as Extension Manager and the problem may be somewhere else.

I updated my OS 2 hours ago. Should I try again?

[oscfdezdz]

You can try although that shouldn't be the problem.
Can you install gnome-extensions-app from a terminal with dnf? (sudo dnf install gnome-extensions-app) Maybe that will solve the problem, when you check that Extension Manager is working properly, you should be able to uninstall it.

I've updated a Fedora 41 machine to try to replicate the issue but it's working as expected.

[oscfdezdz]

A reboot may also fix it if you didn't do one after upgrading, it's possible that related system files were modified.

Same error here on openSUSE Tumbleweed. I updated the system just last night.

@nicolito128 From the log you share, it isn't the same issue and I think it should be fixed by #765 for the next stable release 😄

[nicolito128]

Oh, sorry for the confusion @oscfdezdz and thank you for pointing out the PR 😄

Hi everyone, I have the same issue. Al my extensions are unsupported and gives me the same pop up error message. I'm on Pop Os Cosmic 24.04.

Hi everyone, I have the same issue. Al my extensions are unsupported and gives me the same pop up error message. I'm on Pop Os Cosmic 24.04.

@Akirah10 Cosmic doesn't support GNOME Extensions, as it's no longer based on GNOME. It's a completely different desktop environment rewritten in Rust...
Therefore this error (different from the first reported) is to be expected.

[Akirah10]

Thank you so much for the response. Yes, doing some reading later on and learn that, I didn't knew that, I thought that it was based in the original OS. Again, thank you for the response, appreciated. Alexander Parada. On Sun, Mar 23, 2025 at 9:59 p.m., Gabriel ***@***.***> wrote: Hi everyone, I have the same issue.
