Grafana server won't start after upgrade to version 9.4.x

On test server din an upgrade to new version of Grafana-server, first to 9.4.2 then to 9.4.3. After that grafana service won't start, with error on syslog:

daemon.warn supervise-daemon[17574]: /usr/sbin/grafana-server, pid 17575, exited with return code 1
...
daemon.warn supervise-daemon[17574]: respawned "/usr/sbin/grafana-server" too many times, exiting

If I try to launch manually grafana-server or even grafana-cli, it output error:

Error locating grafana: exec: "grafana": executable file not found in $PATH

Other than update/upgrade, no other changes were made.
