Same in the Netherlands.

So only big cities and no countryside where immigrants are actually needed to keep the farm running?

Remove the .4 from “go 1.23.4” or replace it by .2. It probably does not need the latest go patches to compile

I have had this before in Go when I had an older version of Go installed but the dependency needed a newer version. It then tries to download a temporary tool chain of a new Go version to compile the dependency (or whatever it is doing). For me, that failed. What did work was upgrading Go to the latest version.

You can check what your installed Go version is by

go version

If it is lower than 1.23.4, upgrade it.
