Mimir from grafana ubuntu / debian repo service failed to start

[waleedsaud]

After install mimir from grafana debian/ubuntu repo it failed to start :

systemctl status mimir

● mimir.service - Horizontally scalable, highly available, multi-tenant, long term Prometheus.
     Loaded: loaded (/lib/systemd/system/mimir.service; disabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Sat 2022-11-19 18:03:28 UTC; 33s ago
       Docs: https://grafana.com/oss/mimir/
    Process: 8429 ExecStart=/usr/local/bin/mimir --log.level $LOG_LEVEL $CUSTOM_ARGS (code=exited, status=217/USER)
   Main PID: 8429 (code=exited, status=217/USER)

the reason is that the user in the service file is not created :

[Unit]

Wants=network-online.target

[Install]

As you can see in this error log :

Nov 19 18:03:27 ubuntu-focal systemd[8429]: mimir.service: Failed to determine user credentials: No such process
Nov 19 18:03:27 ubuntu-focal systemd[8429]: mimir.service: Failed at step USER spawning /usr/local/bin/mimir: No such process

When I searched for the user it was not created :

root@ubuntu-focal:~# grep mimir /etc/passwd
root@ubuntu-focal:~#

👋 Thanks for opening this issue. The RPM and DEB packages are currently maintained by the community, since Mimir maintainers don't use them directly. A couple of follow up questions:

• What do you suggest to solve this problem?
• Willing to pick up the follow up work?
