Hello, Running into an issue when trying to update Mattermost from 5.13.1 to 5.25.0 . OS: Debian 8.11 CP: Plesk Fairly new to command line usage but advanced knowledgeable enough to be catching on. Using [Redirect](https://docs.mattermost.com/administration/upgrade.html) as guide: receiving an error at step 5 that says ``` Failed to stop mattermost.service: Unit mattermost.service not loaded. ``` Any help and advisement on how to continue with upgrade would be appreciated ---

Hi, @ashleys Since the error mentioned that `mattermost.service` was not loaded, can you confirm that the status as of now? ```auto sudo systemctl status mattermost.service ``` Also, can you confirm the content of the mattermost.service as well? ```auto cat /lib/systemd/system/mattermost.service ``` I am just trying to understand if there was a mattermost service that was set up in the first place. Thanks. ---

Thanks for responding @ahmaddanial It’s up and running at: [https://patentventures.dev/mattermost](https://patentventures.dev/mattermost) Attaching the results ``` mattermost.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) ``` `cat: /lib/systemd/system/mattermost.service: No such file or directory` But also after some investigation here’s what I found in Plesk. Seems to be a different name? [Screen Shot 2020-07-23 at 6.01.46 AM|690x347](https://forum.mattermost.com/uploads/short-url/i7DdUIR9uNzZQRPc0VZbKrTwPur.png) ---

Hi, @ashleys You are welcome. The error means that there was no mattermost service configured in the first place to use `systemd` for starting and stopping the service. I can confirm that the instance is up and running on my end too: ![image](https://us1.discourse-cdn.com/flex020/uploads/mattermost/original/2X/7/738aa11e4736cb126b78fc0e357ef80695860980.jpeg) Moving back to the upgrade process, may I know how Mattermost was installed? Were you referring to the [Installing Mattermost on Debian](https://docs.mattermost.com/install/install-debian.html#installing-mattermost-server) originally? Since step 5 in the upgrade documentation only highlights for Ubuntu and RHEL, I don’t think it applies in this case. Also, what happens when you stop the Mattermost service from Plesk and proceed with the upgrade? Does it go through? ---

@ahmaddanial ahh I understand. It was installed using the [Plesk extensions catalog](https://www.plesk.com/extensions/mattermost/) And no I didn’t try stop the service from Plesk. I was afraid of messing something up. Should I try to proceed with the update instructions, skipping #5, and using Plesk to stop and restart the service? ---

Hi, @ashleys As long as you have the Mattermost [backup](https://docs.mattermost.com/administration/backup.html) handy for roll backs, I’d say go for it. If you have run into any issues along the way, capture the `mattermost.log` and the error that you are seeing on your end (console and UI). Roll back if necessary. ---

hi @ahmaddanial, I think it went through. How do I check the version? In the mobile app it says the serve version is 5.25 but just wanted to make sure that was correct. ---

Hello, @ashleys Log in to the desktop / web app. Click on the 3 line icon and open up **About Mattermost**. You should be able to confirm that it is upgraded properly. For example: ![image](https://us1.discourse-cdn.com/flex020/uploads/mattermost/original/2X/5/5838d44ac939c49e08acda03923d88ab680f9b81.png) Does it show the right one?
