Go version 1.20 specified in config file causes linting against Go 1.2.

Welcome

• Yes, I understand that the GitHub action repository is not the repository of golangci-lint itself.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).

Description of the problem

First time user of GolangCI-lint action.

In the .yml config file I wrote the following:

jobs:
  golangci:
    name: lint
    runs-on: ubuntu-latest
    steps:
      - uses: actions/setup-go@v3
        with:
          go-version: 1.20

...which caused the action to download Go 1.2, not 1.20:

Run actions/setup-go@v3
  with:
    go-version: 1.[2](https://github.com/coachinabox/uptime-monitor/actions/runs/4116180025/jobs/7105883087#step:2:2)
    check-latest: false
    token: ***
    cache: false

Changing go-version: 1.20 to go-version: 1.19 correctly uses Go 1.19.5.

Version of golangci-lint

latest (1.51.1 at the time of writing)

@vaughany Don't think this is a golangci-lint issue. See comment from the setup-go repo:

actions/setup-go#326 (comment)

[...] I think it is an expected behaviour. You need to specify version like this go-version: '1.20'. [...]

[vaughany]

@Loddan You are correct. Thank you for pointing this out. I had searched through the issues but not on the 'setup-go' repository.

I can confirm that go-version: '1.20' does work as expected. Thank you!
