I tried downloading the deb file from the official page as well, and it’s hash doesn’t match either.

sha256sum mattermost-desktop_5.3.1-1_amd64.deb

Hi @colin.mcinnes and @theoreticMK and welcome to the Mattermost forums!

This is a known issue unfortunately, see also this forum topic:

Mattermost is still working on a fix for that, I’ll update the linked topic once that fix is available and will close this one, please watch the other one for updates.
