I bought a new laptop (Dell 3493) and moved my installation disk from my old one. I had in it the 18.04 LTS and after some troubles I decided to update to 20.04 LTS. I got everything to work except those 3 programs, which never start.
This is what I got with Shotcut:

No appenders associated with category qt.network.ssl [Warning] <> QSslSocket: cannot call unresolved function SSLv23_client_method No appenders associated with category qt.network.ssl [Warning] <> QSslSocket: cannot call unresolved function SSL_library_init Segmentation fault (core dumped)

This is what Kdenlive shows:

MLT ERROR: "[consumer sdl2_audio ] Failed to initialize SDL: Could not setup connection to PulseAudio"

org.kde.knotifications: Audio notification requested, but sound file from notifyrc file was not found, aborting audio notification Segmentation fault (core dumped)

And this is what I got from Blender:

Writing: /tmp/blender.crash.txt Segmentation fault (core dumped)

About Kdenlive, when I use the snap version on the official ppa got as well a Segmentation fault (core dumped). I couldn't find proper answers in the web (by the way, I've tried to reinstall an reboot a couple of times those apps).

  • Ok, I was considering that. I'm going to create a clean instalation of 19.10 to see if everithing works better. Do you think would be necesary to create a new /home disk as well? I have them separated. – mekax May 15 '20 at 04:23

For kdenlive had the same problem. I resolved it using the appimage from the official web site. Maybe you can do the same with blender and shortcut…

  • remove kdenlive
  • download appimage from the official website: wget https://files.kde.org/kdenlive/release/kdenlive-20.04.1b-x86_64.appimage -O ~/Downloads
  • install appimage library: sudo apt install libappimage0
  • add execution bit to the .appimage file: chmod +x ~/Downloads/kdenlive-20.04.1b-x86_64.appimage
  • execute the file ~/Downloads/kdenlive-20.04.1b-x86_64.appimage

  • Thanks, I will try! I did as @Nmath said and made a clean installation of Focal Fossa. I got everything working just fine, but I triyed to install some audio packages from the Ubuntu Studio Installer app, and also I installed Virtual Box and Genymotion. After that Kdenlive again got broken (but not Blender or my video reproduction, so it is a good sing). I guess there's some difficulties between Kdenlive and Jack, but we will see. – mekax May 27 '20 at 19:57
  • UPDATE: about an easy solution to the troubleshouting between Kdenlive and Jack, see here: https://medium.com/@ayubaswad/simple-way-to-fix-kdenlive-no-sound-3923c795788d Seems to work for me. – mekax May 27 '20 at 21:39

The problem seems not limited to three programs mentioned in the question. According to this answer it is a bug in mesa drivers. Adding following line to .profile seems let the programs start (I can confirm it for Blender and Kdenlive)

MESA_LOADER_DRIVER_OVERRIDE=i965

However it is not a proper fix and we have to wait for the problem to be solved in drivers.
