I need help, apps like marble, plasamtube not working cause missing libtheoraenc.so.1

Help
1

hello,

i’m having a problem with several applications. marble isn’t running cause of a missing library (libtheoraenc.so.1). this happened several months ago with an update of manjaro. okay sometimes it takes a little bit that apps get unusable until they are up-to-date again. i was waiting for months now and tried to reinstall marble. unfortunately this app is still not running cause this pitty. has someone an idea how to solve it ?
i can run marble with an actual debian12 with plasma 5 but this isn’t a good solution.

This would be a useful topic for the Manjaro Forum.

You would also need to offer some relevant information.

For example, there is Marble as well as Marble-qt in the repos… but also a Flatpak.

So many issues with Manjaro stem from people who insist on running it in an unsupported state (as it’s a rolling distribution, it’s important to ensure your mirrors are up to date and properly synchronised before installing software).

I just installed and opened marble-qt from the ‘extra’ repository with no problem whatsoever. This is not a KDE issue.

The reason I suggest you are likely running your system in an unsupported or improperly updated state is that libtheoraenc comes from the Theora video codec which comes pre-installed with Manjaro:

 pacman -Ql libtheora | grep libtheoraenc.so
libtheora /usr/lib/libtheoraenc.so
libtheora /usr/lib/libtheoraenc.so.2
libtheora /usr/lib/libtheoraenc.so.2.2.1

Using the Manjaro Forum, there are people who can help troubleshoot (this error is related to your packaging, not KDE) as well as advise you and teach you the proper way to manage and update your system.

thanks for your fast reply. checking for the lib shows exactly the same

pacman -Ql libtheora | grep libtheoraenc.so

libtheora /usr/lib/libtheoraenc.so
libtheora /usr/lib/libtheoraenc.so.2
libtheora /usr/lib/libtheoraenc.so.2.2.1

meanwhile i figured out that it might/must be something with the graphics of the amd-gpu of the used imac. i’ve got 2 systems, one an pc with an nvidia-gpu where marble runs without problems and the other, an older iMac 12,2 that i use as daily driver.
i don’t expect any help from the manjaro-forum.
but thanks anyway

i found the problem.
for whatever reason the package “ffmpeg-amd-full” was installed (cause it’s a amd-gpu). after removing this package and installing the ordinary “ffmpeg” package the problem is gone.
