Hi all,

I followed the instructions on docs.mattermost.com/upgrade/upgrading-mattermost-server.html exactly in an attempt to upgrade our mattermost server. when I try to execute the command at step 11, mattermost fails to start.

I’m a complete ubuntu noob, so anything deviating from the upgrade manual is quite a challenge for me.

Please let me know if this is enough info or if I need to provide some more.

Any help toward resolving this issue is appreciated.

Kind regards,
Robin.
