Upon an aptitude update and dist-upgrade, then installing mnemosyne, the program fails to start with the following errors: libpng warning: iCCP: known incorrect sRGB profile libpng warning: iCCP: known incorrect sRGB profile libpng warning: iCCP: known incorrect sRGB profile libpng warning: iCCP: known incorrect sRGB profile libpng warning: iCCP: known incorrect sRGB profile QIODevice::write (QProcess): device not open [4094:4094:0100/000000.061450:ERROR:broker_posix.cc(41)] Invalid node channel message [4096:4096:0100/000000.061424:ERROR:broker_posix.cc(41)] Invalid node channel message Some updates to nvidia were held back (due to apt-listbugs, and an another issue causing opencl issues with the update which was pinned and prevented.) An out-of-repository 3D application was tested, as well as glxgears, and Blender (Sid version, Blender 2.79) ruling out a general issue with OpenGL related to holding back the update. A second computer which also runs Sid, but has not been updated for one week, does not exhibit the issue (the program runs normally.) It is also possible to access the web server and sync server aspects of mnemosyne, further implying that the issue is related to the GUI in some way. Another Qt application (Krita) was tested and found to start and operate normally, including saving image files (an error found in Arch once related to corruption caused by Deepin packages messing with Qt's image libs, though not a present issue on Debian), ruling out a general crash with Qt applications. Both systems are running Cinnamon. The other system was first installed as XFCE, then replaced with Cinnamon and XFCE group removed. The second system (which exhibits this error) was installed as Cinnamon from the beginning.
I also had this problem. (Moreover mnemosyne ends with segmentation fault) But after installing python3-opengl mnemosyne start to work. So it would be worth to check dependencies. KJ
I had the same problem; had to install package libgl1-mesa-dev to get it to start.
