I have been using Cryptomator successfully for some time. Then I upgraded my Ubuntu to 18.04 LTS (what may or may not be an important factor here). Then I discovered Cryptomator is not able to launch.
I am getting an interesting stacktrace on the console. Any hint what goes wrong would be welcome.
The console output looks like this:
/usr/bin> ./cryptomator.sh
