im installing a VM with Ubuntu… i follow the instruction to compile… it generate /bin folder with some folders… and mattermost and mmctl files…

in my live server… i replace the mattermost ( and apply roles permissions)

but cant run

sudo systemctl start mattermost.service

-- 
-- The job identifier is 8139.

i rename this to mattermost2 and the older mattermost_old rename to mattermost and it work.

i try with /server/bin mattermost file and with /server/bin/linux_arm64 too… and nothing

@KatiaSishost what are you compiling, and how? What architecture is your hardware? “Exec format error” can occur if you compile on one arch and attempt to execute on another. What does uname -i say? And, do you have a specific reason to compile your own vs. just download the tarball? https://docs.mattermost.com/install/install-tar.html

Hello, I was able to solve it, the problem was the dependencies that I had to update to Ubuntu 22.04 and it works perfectly…

The only drawback is that only the Team version is compiled when I actually need the Enterprise to make some add-ons for that version since we are going to have the license…

So I’m still looking at what to do with that issue.
