SDK manager hangs on Linux


My watch face stopped working (I think after an update) so I wanted to switch to the latest SDK and rebuild.

However the Linux SDK manager in developer.garmin.com/.../ hangs when I run it. I can see in htop the process runs, but it doesn't use CPU and RAM usage doesn't increase. It seems to get stuck waiting for something.

Please can Garmin devs fix the Linux SDK manager so that we can update our toolchains?

Thanks.
