I have installed MC 33 on Ubuntu 24.04. The software would not start. When starting in terminal, The following messages appear:

What could it be?

Take a look at this thread.

Did you use installJRMC?

[ashchemelinin]

No, intallJRMC did not work. I had to follow manual procedure. But it went smooth...

[BryanC]

No, intallJRMC did not work.

I could not replicate this in Ubuntu 24.04. Could you please run installJRMC --debug and provide the output?

[ashchemelinin]

Appears the installJRMC script worked and installed MC. But if it's still segfaulting that's something not related to it.

What's the specs of the PC you're trying to run MC33 on? CPU? GPU?

[bob]

Also, try removing the user folder under the users .jriver/Media Center 33 (keeping in mind that if you don't have a license you will lose trialware).
Make sure the ownership under .jriver is correct. (never run under sudo)
Don't interrupt MC on it's first start (it will be slow because it's copying a lot of stuff into user space)

[ashchemelinin]

System parameters are:
- Ubuntu 24.04.2 LTS
- Processor: AMD Ryzen™ 5 7600 × 12
- GPU: AMD Radeon™ RX 580 Series

JRiver MC30 works without any issues...

[ashchemelinin]

Also, I did remove the directory as suggested. When attempting to start JRiver, I was asked for license. After this, the directory was re-generated. Not other changes. Exactly the same behavior as first time.

[bob]

MC30 has older library requirements.
Can you install gdb and run it under that?
gdb mediacenter33
then
run
IIRC.
When it crashes do a
bt full
The lines at the top are the most important, especially the one where the crash actually occurs. Can you post them here?
Thanks.

[bob]

Would you do the
bt all
command when it segfaults?
It will return the stack trace.
Thanks.

Note: Just did a fresh install of 24.04, used InstallJRMC and it works fine.

[npreining]

I have similar issues, and in my case it is related to KWin/Wayland, ie. when you run the KDE Plasma desktop on Wayland. In this case, MC crashes every single time.
Plasma on X11, or Gnome on Wayland, both work, though.
Maybe you are in a similar situation.

[Awesome Donkey]

If they're using Kubuntu (and they did mention using Dolphin, so would make sense it's KDE), if using Wayland you may have to switch to the X11 session otherwise it might segfault.

Also with KDE Plasma + Wayland if you're still getting segfaults you might try Bob's instructions above too to get a stack trace and post it, might help.

[bob]

I just did the default install on a modern machine. Didn't check to see what the XServer was.
