This might be related to [MM on Ubuntu 20.04; sudo?](https://forum.mattermost.com/t/mm-on-ubuntu-20-04-sudo/14143) - not sure if we should work on both issues at the same time.  
Anyways the error message here is that your provided database connection details in your `config.json` file are wrong (the system cannot connect with the details there to your database).  
What installation instructions did you follow?

In the beginning I wrongly followed the server installation instructions - [Deploy Mattermost — Mattermost documentation](https://docs.mattermost.com/guides/deployment.html#server-installation)

Then the desktop installation instructions - [Deploy Mattermost — Mattermost documentation](https://docs.mattermost.com/guides/deployment.html#desktop-and-mobile-app-installation)

Is this issue still relevant here now that we fixed the problem in the other topic?

The issue was fixed in [MM on Ubuntu 20.04; sudo? - #12 by agriesser](https://forum.mattermost.com/t/mm-on-ubuntu-20-04-sudo/14143/12)
