I'm using Azure DevOps (visualstudio.com) and trying to get a Linux Build Agent up and running on a local server. This was working previously, but I upgraded the Linux server from Ubuntu 16.04 to 18.04. That broke my previous build agent.
So I removed the previous build agent and installed an up to date one. The new one registered easily, but when I try and run a build, it fails to check out sources.
Anybody know what might cause this problem, or where I can go for help? I don't manage our Azure DevOps. I'm just trying to get the Linux part working as it was.
Edit: I should note that running ./externals/tee/tf produces zero output (and returns with the same 100 code). Maybe it has something to do with java. I'm running Java(TM) SE Runtime Environment (build 12.0.2+10).
