I'm running Zorin Ultimate 15.3
I have software update set to periodically check for updates and alert me. I still tend to apply updates from the command line only bc. I have a historic (and most likely, irrational) distrust of GUI-based SW updaters under Linux. Regardless ...
For the past week, I get a notice every other day that updates are ready. When I drop to the cmdln and run sudo apt update && sudo apt list --upgradable I'm shown that nothing is needed. However, gnome-software is insisting that there's something to update. When I click on the notification message and Software opens, I see the following:
Sorry, something went wrong: failed to get origin-hostname: Remote "flathub" not found
When I dismiss this, a single item remains in the Software list:
GNOME Application Platform version 40
The GNOME runtime is appropriate for any application that uses the GNOME platform. The runtime is layered on top of the Freedesktop run...
When I click on this item, I get the following:
runtime/org.gnome.Platform/x86_64/40 No update description available.
So apt thinks there are no updates and Software thinks there is but can't really tell me about it.
What's up with this? What should I do?
those themes are flatpak packages to flatpak apps. you can safely remove them.
Ofcause you can also keep them, if you want to install any other flatpak.
No. The Zorin Themes are included in Flatpak but also included in apt and in your /usr/share/themes directory. You safe to remove those if you are removing Flatpak since only Flatpak apps would call on those Flatpaked Zorin themes.
