Works here:

• OS: Debian 10 (Buster)
• Native server installation (no docker)
• Plugin version 1.1.0

This might be a musl issue because the mattermost docker image is based on Alpine.
When i run manually the binary i got :

Error relocating ./plugin-linux-amd64: __vfprintf_chk: symbol not found
Error relocating ./plugin-linux-amd64: __fprintf_chk: symbol not found

Which might be due to musl lib c.

I found a solution by using gcompat into the docker image.

https://git.adelielinux.org/adelie/gcompat

apk add gcompat and 🎉 ! It's working !

@Aguay-val could you help advise more detail on your solutions to make the collabora server in docker work with mattermost 😉 ?

[Aguay-val]

For now, i just install the gcompat package into the docker image.
You could do something like:

FROM mattermost/mattermost-team-edition
RUN apk add gcompat

Then use the image you just built and then it should work.
