@jjohansen @georgiag Thanks for the replies and hints. I didn't have
apparmor profile and that fixes the problem. (I have created feature
request for electron-builder https://github.com/electron-
userland/electron-builder/issues/8635)
Without apparmor profile, an Electron.js app complains: The SUI
I have 4.0.1really4.0.1-0ubuntu0.24.04.3 and still have the
"LaunchProcess: failed to execvp" problem. We a custom Electron app
packaged into a *.deb file. The problem occurs, when the installation
dir has a space in the path, e.g. "/opt/Custom App". When we make
installation into "/opt/CustomApp"
