So you want to keep your golang up to date at all times?
Add this to /bin/go-update, and stick it in your crontab as a daily job, and you will always be up to date.
Rework as needed for your favourite Linux/os distro..
#!/bin/bash
cd /tmp
CVERSION="$(curl -s https://go.dev/VERSION?m=text | grep -o 'go[0-9.]*')"
wget "https://go.dev/dl/${CVERSION}.linux-amd64.tar.gz"
rm -rf /usr/local/go
tar -C /usr/local -xzf "${CVERSION}.linux-amd64.tar.gz"
rm "${CVERSION}.linux-amd64.tar.gz"
go version
Njoy!!
