What I’ve Tried

An attempted upgrade failed and screwed up the desktop environment so I couldn’t read the error message.
I’m afraid of installing the upgrade for fear of breaking the compatibility between the installed components of Ubuntu Studio and those of standard Ubuntu.

Ubuntu Studio is Ubuntu. Since the popup component is shared with Kubuntu, it says “Ubuntu” to be more generic.

Ubuntu Studio has no additional repositories and is not a separate distribution.

There will be some theming issues upon upgrade as there’s a move from Plasma 5 to Plasma 6 along with some cosmetic issues from the move from the Materia theme to the Orchis theme. However, that’s as easy to fix as reapplying the theme from System Settings.

Many thanks for the quick response!

I reattempted the upgrade and got the following warning:

which led me to break off the upgrade. I have installed Firefox directly from Mozilla’s repository because:

  1. I had no end of access problems with the flatpak version offered in the standard repository.
  2. The flatpak version is often older, and I like to have the latest security patches.

What I don’t understand is the apparently unnamed module installed from “unknown origin”.

Here are the sources I see in Discover:

I have also installed Synaptic Package Manager, which gives me more granulaity and made it easier to install Firefox from Mozilla.

How can I find out what the second mysterious module in the complaint is?

Honestly, I’d just ignore it. Those dialogs have been known to have false positives.

The other thing you can do is upgrade from the terminal to see even more granularity: do-release-upgrade is the command there.

Thanks for the tip!

Trying the update from the console revealed the mysterious module to be go-mtpfs:

Go-mtpfs is a simple FUSE filesystem for mounting Android devices as
an MTP device.

I did not knowingly install this. I have an Android smartphone, but have never connected it to this Linux PC and don’t intend to do so.

apt rdepends go-mtpfs

revealed:

Reverse Depends:
Recommends: kubuntu-desktop
Recommends: kubuntu-desktop
Recommends: ubuntustudio-desktop
Recommends: ubuntu-budgie-desktop

which suggests to me that it was installed as part of Ubuntu Studio.

Should I uninstall it before updating or just go ahead?

No. As you can see:

Recommends: ubuntustudio-desktop

Anything that is a “Recommends” is basicaly a soft-dependency, meaning it’s pulled-in by default but isn’t absolutely required if you want to remove it later.

I started the update process, ignoring the warnings, After about an hour the screen went balnk and the computer appeared inactive and didn’t respond to mouse or keyboard. Because of the warning that the update could take several hours, I left the PC in this state for over 12 hours. I then pressed the power button, upon which the screen came on and appeared to show a regular shutdown.

Restarting the computer shows the regular splash screens I used to see while booting, but then the screen goes blank instead of showing the login screen. Again the PC does not appear to respond to keyboard or mouse.

I am able to boot to GUI from a USB stick containing the original Ubuntu Studio 26.04 release. How should I proceed?
