How can I fix this GStreamer update bug on a fresh install of Kubuntu 23.04?

I've got a brand new Lenovo Ideapad which I just installed KUbuntu 23.04 onto. However, the package manager isn't updating everything. Specifically three packages, all related to GStreamer, are failing to update.

The specific warning message is:

Package failed to install:

Error while installing package: trying to overwrite '/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstcamerabin.so', which is also in package gstreamer1.0-plugins-good

The advice is to try again later, but if it's attempting to overwrite a package, I'm not sure that that will have any affect.

When I attempt to remove GStreamer and reinstall it from scratch (sudo apt remove gstreamer1.0-plugins-good), I'm greeted with a list of missing dependencies, and the advice to run `apt --fix-broken install, which wants to download about 700 kB. That's fine, but it's again stopped by the same error in doing so.

Verbatim after --fix-broken:

It's the same deal with other commands, but if anyone needs specifics, I can look it up.

The laptop/graphics tablet works fine, but I would really like to get this resolved, and I'm personally running out of ideas. Can someone give me a pointer on what to do next to resolve this?

The only software I've installed is Krita, Blender 3.6 (by direct download, not through a repo), and OpenToonz via snap. It's a particularly fresh machine, I never put GStreamer on it myself save by installing KUbuntu.

As a side note, I attempted to install OpenToonz through Flatpak, but it couldn't find the repo, so I went with Snap. My issues only came up after installing updates, and at this point I can't seem to install anything through apt or the software center.

After taking another look, it appears as though `libgstreamer-plugins-base1.0-0` needs to be greater than 1.22.3, but won't go above 1.22.1-1ubuntu1. Perhaps this is something that just needs to be integrated into the repo before I can continue?

So, it's finally working, and while it's difficult to be sure, the problem seemed to stem from Snap somehow.

I went ahead and first attempted to uninstall absolutely everything that was causing issues. This quickly became quite a list:

sudo apt remove gstreamer1.0-libav gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-pulseaudio gstreamer1.0-x libgstreamer-gl1.0-0 phonon4qt5-backend-gstreamer gstreamer1.0-gl libgstreamer-plugins-bad1.0-0 libgtk-4-media-gstreamer libqt5multimediagsttools5 libqt5multimedia5-plugins elisa

But I reasoned that if a dependency was missing or corrupted, then I wasn't getting full use out of it anyway. However, phonon ended up introducing another ourouborous-type unfixable error. So, I plugged in my original LiveUSB, and attempted to, as nondestructively as possible, reinstall KUbuntu.

System files and settings were preserved, including config files. The first thing I did was install all available updates, then I got back to work. Blender was still on there because I just grabbed the binary, as is my custom. Krita needed to be reinstalled, through the Discover Software Center, but remembered all of my settings and my documents, which is great.

I even restarted to be sure, the old GStreamer bug had not come up. So, I went ahead and attempted to install OpenToonz with flatpak, instead of snap. I had to add flathub:

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

After that, I could simply install the flatpak packages necessary for OpenToonz:

flatpak install flathub io.github.OpenToonz

This took a little while, but I now have Blender, OpenToonz, and Krita, all functioning on a properly updating system.

The one major difference is that I installed with Flatpak instead of Snap; what Snap's issue is, I can't be sure.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
