Two things.

It looks like there's a bug in the go-debian script this exposed. It turns out that go version emits a version of go1.17 instead of go1.17.0 like you'd normally expect.

Therefore this line

if [[ "1.16" > "$(go version | grep -oP 'go\K[0-9]+\.[0-9]+\.[0-9]+')" ]]; then

needs to make the last section of the semver optional. I think this should do it:

if [[ "1.16" > "$(go version | grep -oP 'go\K[0-9]+\.[0-9]+(\.[0-9]+)?')" ]]; then

Go 1.17 recommends using "go install" for CLIs instead of "go get", but older versions still need the old syntax. So this detects the actually installed version (since we may have skipped installing go itself) and only uses go install for go 1.16+.

The other is a minor tweak inline...
