Hi,
this might be the wrong place for the issue, if so, then please point me to the right one.

Problem: The script install_tendermint_ubuntu.sh does contain the following line:

GO_VERSION=1.12.0

That variable is used to build the download URL for go:

curl -O https://storage.googleapis.com/golang/go$GO_VERSION.linux-amd64.tar.gz

unfortunatly there is no file https://storage.googleapis.com/golang/go1.12.0.linux-amd64.tar.gz

Changing the version to:

GO_VERSION=1.12

fixes the problem.

Best regards,
Guido
