Troubleshooting

ubuntu 24.04 core dump

Error message likes:

The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I’m aborting now. You need to make sure that dev/shm/tmpdir.mount_Deepl-iCQgY6/chrome-sandbox is owned by root and has mode 4755.

just run with parameter:

./Deepl-Linux-Electron-1.5.0.AppImage --no-sandbox

see: Doesnt’ work with Kubuntu 24.4
