[KDE] how to identify and install missing (uninstalled) packages

scaptal · August 25, 2025, 11:14am

Background/Issue

Recently I had some issues with my packages, and after trying a few different things I decided to remove some packages manually (Had some conflicting packages between System and Terra.
The specific package removal was:

sudo dnf remove ghostty
sudo dnf remove libavcodec
sudo dnf remove LCEVCdec
sudo dnf remove libavdevice
sudo dnf remove falcond-profiles
sudo dnf remove ffmpeg
sudo dnf remove steam steam-device-rules

This seemed to work decently well, except for the fact that my desktop doesn’t show my background anymore (and understandably throws an error) and KDE-connect crashes on launch.

Plasmashell/Background

I ran the plasmashell --replace command to see what the specific error was and got the following output.

kf.plasma.quick: Applet preload policy set to 1
QQmlComponent: Component is not ready
kf.plasma.quick: Error loading the wallpaper QList(file:///usr/share/plasma/wallpapers/org.kde.image/contents/ui/main.qml:11:1: Cannot load library /usr/lib64/qt6/qml/org/kde/plasma/wallpapers/image/libplasma_wallpaper_imageplugin.so: libexiv2.so.28: cannot open shared object file: No such file or directory
    import org.kde.plasma.wallpapers.image as Wallpaper
    ^)
kf.plasma.quick: "file:///usr/share/plasma/wallpapers/org.kde.image/contents/ui/main.qml"
 "Error loading QML file.\n11: Cannot load library /usr/lib64/qt6/qml/org/kde/plasma/wallpapers/image/libplasma_wallpaper_imageplugin.so: libexiv2.so.28: cannot open shared object file: No such file or directory\n"

    import org.kde.plasma.wallpapers.image as Wallpaper
    ^)
kf.plasma.quick: "file:///usr/share/plasma/wallpapers/org.kde.image/contents/ui/main.qml"

kf.plasma.quick: File name empty!
QQmlComponent: Component is not ready
kf.plasma.quick: error when loading applet "com.dv.fokus" QList("Error loading Applet: package com.dv.fokus does not exist.")

The first issue which catches my eye is that I seemingly removed some dependency for the file /usr/lib64/qt6/qml/org/kde/plasma/wallpapers/image/libplasma_wallpaper_imageplugin.so (which would explain the missing wallpaper functionality).

KDE-connect

At startup KDE-connect also crashed due to a segfault with the error backtrace:

Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault

Fin

Hopefully some of you might have an idea of how I can fix it.

I was debating trying to see if the issue would resolve itself if I reinstalled some of the kde related dnf groups, but thought it wiser to first ask for some advice before messing with the system any further.

Specs

kernel: Linux 6.15.10-200
OS: Fedora Linux 42 (Plasma spin)
Desktop Environment: KDE Plasma 6.4.4
Window Manager: Wayland

That lib is provided by exiv2-libs.

There should be no major issues if you install the KDE groups:

sudo dnf group install kde-desktop kde-apps kde-media kde-pim

You can also run sudo dnf --refresh distro-sync to sync your packages to the available packages on the repo (e.g., this will downgrade testing packages).

scaptal · August 25, 2025, 12:08pm

Thanks for the response, sudo dnf --refresh distro-sync doesn’t give any packages to install, which feels somewhat strange but oh well.

One thing which kindof worries me with the group installation is the sheer number of packages that would install (476) which doesn’t seem logical if I’m simply installing stuff I already have.

I can’t post the full output as its to large, but some snaps are here:

$ sudo dnf group install kde-desktop kde-apps kde-media kde-pim

Do these operations install extra packages which are not there by default?

pg-tips · August 25, 2025, 12:14pm

If “by default” means “after using the installer from a Fedora KDE Plasma live ISO” then yes, some extra packages will be installed which are excluded from the default install, e.g. Digikam.

In fact, Digikam in particular pulls in some heavy dependencies (e.g. proj-data-us which isn’t really needed but is a transitive weak dependency of Digikam).

However, some of the packages it’s trying to install for you seem surprising. For example, Ark, Skanpage and Spectacle should be part of a standard Fedora KDE install. Had you intentionally removed them, and/or had you installed in a customised way, e.g. from the Everything ISO?

pg-tips · August 25, 2025, 12:19pm

It would be interesting to see exactly what got removed in those 7 sudo dnf remove commands.

If you do dnf history list you should be able to see the transaction ID for each of them.

Then dnf history info 123 (replace ‘123’ with the correct transaction ID) will show what was removed in each. Do any of them seem to have removed unexpected packages?

snowyyd · August 25, 2025, 12:43pm

This is completely normal. distro-sync performs operations (upgrade, downgrade) on installed packages. It is simply a way to synchronize your installed packages with the packages available in your enabled repositories.

The fact that this command does not return any packages is a good thing, as it means that the packages you have installed correspond to the versions available in the repositories you are using.

The command I specified installs all the packages defined within those groups (kde-desktop, kde-media, etc.).

In a “default” Fedora 42 KDE installation (at least using netinst), those are the groups that are installed when you select “KDE” as the Desktop Environment. The fact that these groups list a large number of packages means that some of these groups may not be installed on your system, as they are not strictly necessary for KDE to function (for example, the only necessary group is kde-desktop). However, the KDE ISO may differ slightly.

My recommendation is the same as @pg-tips’s: it would be a good idea to review the transactions you made with dnf5 and dnf4 (since, if I remember correctly, PackageKit still uses dnf4).

ilikelinux · August 25, 2025, 2:08pm

Even if you removed Terra you could have things from there installed. You would have to specifier seperately to remove them.
dnf list --extras gives you some hints

scaptal · August 25, 2025, 2:24pm

Okay, I’m learning a lot about debugging dnf transactions, so thats already great.

It seems like this was indeed removed when I ran dnf remove libavcodec. I had assumed that it would not remove any packages which other sources relied on, but I guess that was not an incorrect assumption on my part.

It seems like the libavdevice and libavcodec packages in particular caused a lot of access packages to be removed.

I do find this strange though, seeing that both these packages where (if memory serves me right) provided to me by Terra. But their removal caused packages from other repositories (which where still needed in different parts of my system) to also be removed.

I’m not sure where my mental model of how dnf works is faulty, but its surely faulty somewhere…

Also, w.r.t. packages which are “unexpected” to have been removed, I’m not fully sure, as I don’t quite know what the normal package set looks like.

Some packages which do still seem strange would be:

mesa-libFLU-0:9.0... since I thought this package was partly required for nvidia drivers.
seemingly exiv2-libs-0:... as this now breaks other parts of my system.
All qt6 packages, as I thought those where used for KDE widgets.

Once again, I’m not very knowledgable on what packages should and should not exist in a well working linux system, so in case anyone wants the full output of these transactions its here:

I tried to simply remove all

I personally tried to find all packages installed via terra with dnf list --installed | grep terra and remove the packages mentioned there, would that not also suffice?

edit: I also tried dnf list --extras and there was no output, so I think all extra packages are removed currently.

pg-tips · August 25, 2025, 2:54pm

Agreed, I have all those on my (reasonably vanilla) F42 KDE system. I don’t think those would have been legitimately removeable.

I also am not too sure how to debug this further.

Have you changed anything in your /etc/dnf/dnf.conf ? (Not saying this is the problem, just that it’s useful information for anyone investigating.)

scaptal · August 25, 2025, 3:00pm

I tried removing cache (dnf clean dbcache dnf makecache) and rpm --rebuilddb. This made fedora unaware of my release version, so I did add “releasever=42” into my /etc/dnf/dnf.conf under [main], but thats all (unless the other commands effected the file).

snowyyd · August 25, 2025, 3:06pm

It should not be possible by default to remove a package (pkgA) that is required by another package (pkgB) without also removing that package (pkgB), since pkgA is a required dependency.

For example, if I try to remove exiv2-libs:

admin@fedora ~> sudo dnf remove exiv2-libs

Removing unused dependencies:
[...]

The same happens if I try to remove libavcodec-free (the free version of the package, available on Fedora repos).

I’m not sure how you managed to delete these packages without making dnf to remove plasma-workspace.

In your current situation, I would try to rollback (dnf history rollback) these transactions to try to revert your system to a “working” state.

scaptal · August 25, 2025, 3:58pm

I would like to avoid it if possible.

I had some strange duplicate package issues and version controll issues (between system and repositories), that was in large part also why I did these removals.

Prefferably I’d like to see if my system has any packages with missing dependencies, and install said missing dependencies, but idk if thats possible. (potentially by simply installing the base-fedora-kde packages)

snowyyd · August 25, 2025, 5:51pm

If you want to check for missing dependencies, you can run dnf check --dependencies.

If you want to install the “base KDE” packages again, you can install the default KDE-related groups: sudo dnf group install kde-desktop kde-apps kde-media kde-pim (you need kde-desktop at least).
