I just installed the mariadb in my ubuntu 19.10 by sudo apt install mariadb-server mariadb-client after when I am trying to start the server by sudo systemctl start mariadb.service shell get freeze I have to use Ctl+c to get shell running.
In the status it's showing activating(start)

  • Other services are working fine with systemctl start
~$ sudo systemctl status mariadb.service

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?

permissions systemd systemctl ubuntu-16.04 journalctl
