I try to install mattermost on my Server (ProLiant MicroServer Gen8, VmWare Esxi 6.0; Ubuntu 18.04). I use these Tutorials to install Mattermost on Ubuntu: [https://idroot.net/linux/install-mattermost-ubuntu-18-04-lts/](https://idroot.net/linux/install-mattermost-ubuntu-18-04-lts/) and /tutorials/install-lamp-stack-ubuntu-18-04-lts/ If i use the command: “systemctl start mattermost.service” they get me this answer: Job for mattermost.service failed because the control process exited with error code. See “systemctl status mattermost.service” and “journalctl -xe” for details. If i’m looking at systemctl status mattermost.service, so they tell me this: ● mattermost.service - Mattermost Loaded: loaded (/etc/systemd/system/mattermost.service; enabled; vendor preset: enabled) Active: activating (auto-restart) (Result: exit-code) since Mon 2018-08-20 15:06:06 UTC; 5s ago Process: 4146 ExecStart=/opt/mattermost/bin/mattermost (code=exited, status=217/USER) Main PID: 4146 (code=exited, status=217/USER) Aug 20 15:06:06 mattermost systemd[4146]: mattermost.service: Failed at step USER spawning /opt/mattermost/bin/mattermost: No such process Aug 20 15:06:06 mattermost systemd[1]: mattermost.service: Main process exited, code=exited, status=217/USER Aug 20 15:06:06 mattermost systemd[1]: mattermost.service: Failed with result ‘exit-code’.

Hi @Luphina, thank you for reaching out. Here are some of my initial observations - According to our docs we support Ubuntu 14.04 and Ubuntu 16.04: [https://docs.mattermost.com/install/requirements.html#mattermost-server-operating-system](https://docs.mattermost.com/install/requirements.html#mattermost-server-operating-system). - Here are our docs on how to install each [https://docs.mattermost.com/install/install-ubuntu-1404.html](https://docs.mattermost.com/install/install-ubuntu-1404.html) and [https://docs.mattermost.com/install/install-ubuntu-1604.html](https://docs.mattermost.com/install/install-ubuntu-1604.html). Would you be able to try the installation with one of these versions? ---

No, i’m use another Tutorial, cause i have Ubuntu 18.04. So i thought, that i cannot use the Tutorial on your page. So can i install mattermost on Ubuntu 18.04 or are you only supporting Ubuntu 14.04 and 16.04? ---

Hi @Luphina, I found this Ubuntu 18.04 guide that seems more detailed than the one you linked above. E.g. it lists pre-requisites such as setting up Nginx and SSL certificate: [https://linuxize.com/post/how-to-deploy-mattermost-on-ubuntu-18-04/](https://linuxize.com/post/how-to-deploy-mattermost-on-ubuntu-18-04/). Let me know if the guide is any better - if not, I’ll ask our developers for more help on this. ---

Hey, thank you for this tutorial. Mattermost are running now on Ubuntu 18.04. But i use Apache2 instead of Nginx. So now i have other problems with the WebRTC. I have the button for calls, but it always says “there was a problem connecting the video call”. I’m reading some topics, cause i don’t resolve it. Thanks for your help. ---

Hi @Luphina, Can you help take a look at our docs related to WebRTC: [https://docs.mattermost.com/deployment/webrtc.html](https://docs.mattermost.com/deployment/webrtc.html)? Can you also help take a look at this thread for troubleshooting tips: [How to start WebRTC?](https://forum.mattermost.com/t/how-to-start-webrtc/5032). Some tips include: - adding this value to the config.json `"StunURI": "stun:stun.l.google.com:19302"` , without updating the Janus server or any code changes. - setting the nat mapping in the janus cfg. ---

Hi @amy.blais Yeah, i take this docs, but the WebRTC doesn’t work. I have adding this value to the config.json. I don’t know, where the mistake is. ---

Hi @Luphina, WebRTC is in beta and is unfortunately known to have some issues - can you help review this page and send us any logs / Console errors and any additional relevant details about your environment: [https://docs.mattermost.com/process/support.html](https://docs.mattermost.com/process/support.html)? ---

Hi @amy.blais, What OS and version is the Mattermost server installed? Ubuntu 18.04 What is your Mattermost server version? 5.2 Can you send a snippet of the Mattermost server logs around the time of the incident? No logs Are you running Mattermost in a container and/or using container orchestration? Docker Database Issues MySQL Mattermost is running, i have only issues with webRTC.
