How to install mattermost-app-trello and make it works?

Troubleshooting
1

Hi everyone.

Our team is planning to switch from Slack to Mattermost. We are currently testing some feature we using.

Now we have a self host mattermost running on ubuntu 22.04, and want to make it integrate with Trello.
We found this mattermost-app-trello from mattermost team. :tada:

But we got this message while trying to install it:

Command with a trigger of '/apps' not found.

According to this document, there is no “/apps” in build-in slash commands. So how do we make this work?

Thank you!

I’ll bring this up with the documentation team. Have you tried installing this plugin via the System Console?

You get the /apps slash command from GitHub - mattermost/mattermost-plugin-apps: Powers the Mattermost App Framework

Yes, none of it works.
Attempts to install either through search or manual upload have proven unsuccessful, resulting in an error message like “unable to find manifest file.”

The link in GitHub - mattermost/mattermost-plugin-apps: Powers the Mattermost App Framework section Deploying and Installing Apps also not working. :disappointed_relieved:
