Title: 21.0.61 crashes on Ubuntu 14.04 LTS
Post by: johnd126 on March 20, 2016, 12:15:18 pm
Hi,

I'm trying to set up MC on a Ubuntu server.  I've upgraded my version of the OS to the latest of everything.  I followed the directions in the Ubuntu/Mint post above and it installed cleanly. 

I set up a network share to the music folder on my NAS and am trying to import the mp3s from there.  It imported quite a number of the albums (I would guess around 100 of the 250 albums) and then crashed.  This line was reported in the syslog:

Code: [Select]
vmubuntu kernel: [  206.083913] mediacenter21[3759]: segfault at 38 ip 00007fac8800e414 sp 00007fac76be2a20 error 4 in libpthread-2.19.so[7fac88004000+19000]
Now, a few seconds after launching MC it crashes again with the same line being added to the log.

The pop up crash dialog also includes this info:

Code: [Select]
mediacenter21 crashes with SIGSEGV in __GI___pthread_mutex_lock()
Is there any way to save the text from the crash dialog?

Thanks,
John

There's a crash issue in 20.0.61 for some people, downgrade to 21.0.54 if you know how to.

I haven't done that before. Are there instructions somewhere?

[Edit:] 

Just tried "sudo apt-get install mediacenter21=21.0.54" and returned "Version '21.0.54' for 'mediacenter21' was not found"

For those encountering the crash issue with 21.0.61 on Debian, Ubuntu and Mint you'll have to downgrade MC by downloading the .deb of 21.0.54;

32-bit MC: http://files.jriver.com/mediacenter/channels/v21/latest/MediaCenter-21.0.54.deb
64-bit MC: http://files.jriver.com/mediacenter/channels/v21/latest/MediaCenter-21.0.54-amd64.deb

Then use dpkg to install, here's an example;

Code: [Select]
sudo dpkg -i <path to the MC .deb file>
If it's in the default downloads folder, then this should work...

64-bit:
Code: [Select]
sudo dpkg -i ~/Downloads/MediaCenter-21.0.54-amd64.deb
32-bit:
Code: [Select]
sudo dpkg -i ~/Downloads/MediaCenter-21.0.54.deb

21.0.54 crashed.  Is this a known type of crash with this version?
