I’ve been looking around and so far I haven’t found any information on whether or not mattermost can be installed on Debian Linux 9.

Hi @potatoprince,

In my understanding it should work, we support Debian and different Linux versions: [https://docs.mattermost.com/install/requirements.html?highlight=requirement#mattermost-server-operating-system](https://docs.mattermost.com/install/requirements.html?highlight=requirement#mattermost-server-operating-system).

Did you try with Debian Linux 9 and experience issues? If yes, we can help troubleshoot further.

I was having some issues, but I managed to at least get it running. I have a problem though, the very first time I accessed it and registered a user, it didn’t ask to create a team - hence it’s not in system\_admin group. Manually adding users with cli to system\_admins doesnt work either. Im running debian 9 with apache proxy.

Hi @potatoprince

Does a thread like this seem to describe the issue you are seeing: ["No teams are available to join", how do I create one?](https://forum.mattermost.com/t/no-teams-are-available-to-join-how-do-i-create-one/5084/2)?
