Linux Ver 26.4.30 Timeline is now empty

Bug
,
1

Running Ubuntu 24.04.4 LTS. Tonight Shotcut automatically updated to 26.4.30. When I re-opened my existing project, the timeline shows no tracks. I can play the audio with the spacebar but it appears to be playing in the Preview Player.

The project had three tracks: 2 (empty) video and one audio. Not only are those tracks not shown in the timeline, but adding a new track does not work - the new track does not appear. Tried dragging a new video into the timeline but that doesn’t work.

Restored the default layout with View/Layout/Restore Default Layout - no effect.

At this point, all I’ve lost is a minor bit of editing of the audio track; but I cannot figure out how to move forward with this project - can’t add or remove tracks. Do I just need to start fresh with a new project? How can I keep this from happening again?

The .mlt file is 12.2 kB if you want to examine ti.

I know about it. If you are using AppImage or portable, re-download. A library was missing. If you are on Snap, wait until tomorrow’s update.

Snapcraft is down while trying to fix it:

Ok, thanks.

That one is resolved but snapcraft down again!

Is there a way to add the missing library manually?

The easiest thing to do is get the AppImage or Flatpak.

Otherwise, you can copy the missing lib to /usr/local/lib.
Then, run sudo ldconfig.

That worked for me. Here I attached the lib:

libQt6LabsFolderListModel.so.zip (45.1 KB)

Worked beautifully and I am back up and running. Thanks!

The snap is fixed now. The version will show as 26.5.1

Over the previous few days Ubuntu and Canonical was under a severe, prolonged DDOS attack.
