According to my understanding of these docs:
https://go.dev/doc/go1.21#tools
https://go.dev/doc/toolchain#version
https://go.dev/ref/mod#go-mod-file-go

before go 1.21 it was not allowed to specify the patch version in the go.mod.
so the code in fix cmd:

go/src/cmd/fix/main.go

Lines 78 to 79 in 905b58b

if before, after, found := strings.Cut(majorStr, "."); found {
majorStr, minorStr = before, after

does not handle string 1.21.0.
Existing code also won't work with go 1.21rc1

$ cat go.mod
module reproducer

go 1.21.0

$ cat << EOF > main.go
//go:build OMIT
// +build OMIT

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}
EOF

$ go fix -tags OMIT .
invalid -go=go1.21.0
exit status 2

What did you expect to see?

Expected go fix to remove the deprecated build tag.

What did you see instead?

Error about invalid version.

ok so the workarond is to edit the go.mod after go mod init and remove the last .digit right?

The aforementioned PR is https://go.dev/cl/527342. Not sure why it didn't cross-reference here. 🤔
