This error happens because go1.20.14 doesn't support go1.21.

Run actions/setup-go@v5
  with:
    go-version: ~1.20
    check-latest: false

The Go version format inside the go.mod has changed since go1.21:

• before go1.21 the format was x.y
• after go1.21 the format is x.y.z

Note: the Go version inside the go.mod is the minimal requirement, so the local Go version should be higher or equal to this version.

Your problem is here:
https://github.com/amery/nanorpc/blob/56aa15bd0cf08845ce3ca99e9774cf1a87ca5e15/.github/workflows/lint.yml#L20

You should replace go-version: '~1.20' with go-version: oldstable (recommended) or go-version: '~1.21'

thank you @ldez, that solved the problem. thanks a lot for explaining the x.y.z thing, it's quite annoying.
