Virt-manager error: Error opening SPICE console: No module named 'typing_extensions'

After a recent update on Fedora Silverblue, I can’t launch any VMs in virt-manager. Upon launching, it provides this error message:

Error connecting to graphical console:
Error opening SPICE console: No module named 'typing_extensions'

The error is the same for all VMs. All I can do is shut the machine down. I haven’t found any useful references to ‘typing_extensions’ but there appears to be a Python package with that name? Not sure if that actually applies here though.

Could you provide the output of the rpm-ostree status command?

This looks a lot like: Error opening SPICE console: No module named 'typing_extensions' · Issue #111 · flathub/org.virt_manager.virt-manager · GitHub

This is apparently an issue in the Fedora Flatpak for virt-manager. Is this what you are using?

Awesome, thanks for that find. That did the trick.

I had to remove the Fedora virt-manager flatpak with this command:

flatpak uninstall virt-manager

Then install the other virt-manager with this command:

flatpak install flathub virt-manager

Thanks for the help!
