Grafana-server not starting after upgrade to Ubuntu 20

Grafana

A few weeks ago we started testing an upgrade for our monitoring server that uses mostly Icinga2 and Grafana (w/ InfluxDB) to go from Ubuntu 18.04 to Ubuntu 20.04. All appears to be well expect getting grafana-server to run.

systemctl status grafana-server output:

~$ sudo systemctl status grafana-server
● grafana.service - LSB: Start grafana at boot time

The last entries in /var/log/grafana/grafana.log are form the system shutting down during the Ubuntu upgrade.

Everything appears to be installed/configured according to Grafana Ubuntu install docs

  • deb https://packages.grafana.com/enterprise/deb stable main is included in
    /etc/apt/sources.list.d/grafana.list
  • sudo apt update and sudo apt upgrade grafana state it is current versions
  • checking current package version says is current:
    :~$ sudo apt-cache policy grafana
    grafana:
    Installed: 7.3.6
    Candidate: 7.3.6

Checking config at /etc/grafana/grafana.ini , it appears this file is still in place because it does have items we had set such as hostname. I found 1 other report for the ‘protocol’ error, but it was closed with no resolution. Any thoughts on what to check next?

Thanks in advance!
