Please let me know if you need more information. 1959727 1 metzpinguin 2020-09-23 17:49:43 +0000 We've had the problem before. The libjack is a system library for audio and has to be installed, we cannot integrate it into the AppImage. Maik 1960058 2 caulier.gilles 2020-09-25 05:00:06 +0000 Has Maik said, install libjack from your system to fix the problem as it's a low level library from the system. Gilles Caulier
