According to the description, I understand that some service cannot start, but which one - no idea. It is also obvious that the matter is in the rights, because. under root everything works ok.
How to find out which service cannot start? What utilities can still see the startup process from and to? strace didn’t give me anything useful (probably there is an error there, but I can’t think of it and see what I need)

Answer 1

strace didn’t give me anything useful (probably there is an error there, but I can’t think of it and see what I need)

Start by comparing the logs strace -f -v -e execve,exit,exit_groupwhen you run as root and as a regular user.
