I am running user-level services in Ubuntu 16.04 LTS. For example, I have my test.service located at ~/.config/systemd/user/test.service
I was able to run the service by doing
systemctl --user start test.target
However, when I try to read its log using journalctl, I got this error message:
journalctl --user -u test.service Hint: You are currently not seeing messages from other users and the system. Users in the 'systemd-journal' group can see all messages. Pass -q to turn off this notice. No journal files were opened due to insufficient permissions.
How can I use journalctl for user's specific unit?
