horvath the system golang is from our OS package repos so we can't upgrade that in place without possibly breaking other things.
If you need to install 1.19 then you can install it in your shell user home directory with the following commands:
mkdir ~/opt
cd ~/opt
wget https://go.dev/dl/go1.19.4.linux-amd64.tar.gz
tar zxf go1.19.4.linux-amd64.tar.gz
export PATH=$HOME/opt/go/bin:$PATH
You could also use a version manager like asdf if you'd prefer something a bit more managed.
