Tried to make a git based ISO today. Everything goes well until efiboot step. I got this error message:
mount: work/efiboot: mount failed: Operation not permitted
Here is a screenshot with the error:
- grabbed last copy of EndeavourOS-archiso code
- applied fix_permission.sh
- ran sudo ./build.sh -v
Edit 2 : looks like my old vm was utterly broken. Closing this thread.
