build from source is not working with go1.19, go.mod & docu needs update

[gen2thomas]

What version of Hugo are you using (hugo version)?

Try to build the latest version (0.121.2), made with go 1.21.5.

Does this issue reproduce with the latest release?

yes

go Version

go version
go version go1.19.13 linux/amd64

Description

run build for installation according to documentation:

"Install Go version 1.19 or later"

CGO_ENABLED=1 go install -tags extended github.com/gohugoio/hugo@latest
# github.com/getkin/kin-openapi/openapi3
/home/user/go/pkg/mod/github.com/getkin/[email protected]/openapi3/schema_pattern.go:27:32: compiledPatterns.CompareAndSwap undefined (type sync.Map has no field or method CompareAndSwap)
note: module requires Go 1.20

Since go 1.21 the go version directive should (citation):

• The go line declares a required minimum version of Go to use with this module.
• The go line must be greater than or equal to the go line of all dependencies.
• The go command no longer attempts to maintain compatibility with the previous older version of Go.
• The go command is more careful about keeping checksums of go.mod files in the go.sum file.

I will try to prepare a PR to fix this in go.mod and also for the documentation site afterwards.

I thought the changes for documentation are trivial, but there are many findings for "go 1.19" and additionally an issue for Changes required for v0.122.0 already exist.

@jmooring , how should I proceed?

[jmooring]

Yeah, this changed with f31375d, where we bumped getkin/kin-openapi from 0.118.0 to 0.120.0 (see getkin/kin-openapi#836 for details).

I've updated the documentation site (gohugoio/hugoDocs#2387) and the README in this repository.

@jmooring thanks for your fast response and fix for the docu part. But the go.mod part is still open. I like to prepare a PR and link this issue. So please can you re-open the issue.

Maybe it was my fault to add an issue for 2 different parts - sorry for that.

Ist this still relevant with #11865 being closed and #12012 being merged?
