Tools version:

go1.17

Repro steps:
https://github.com/cloudwego/hertz/actions/runs/13171441602/job/36766483015

Expected behavior:

no error

Actual behavior:

error with EEXIST

[xiaost]

It only happens when the first run we setup a new env.

and the next run will be

Found in cache @ D:\Users\cloudwego\actions-runner\_work\_tool\go\1.17.13\x64

I think it's not caused by go version.
it also reproduced here: https://github.com/cloudwego/hertz/actions/runs/13171441602/job/36766961921

Hi @xiaost,
Thank you for reporting this issue. We will investigate it and get back to you as soon as we have some feedback.

I am having this same error using setup-go@v4:

Successfully extracted go to C:\actions-runner-m0rFq_work_temp\e6f1231e-8acf-471e-acab-3c810beba5f0
Adding to the cache ...
Error: Failed to download version 1.23: Error: EEXIST: file already exists, symlink 'D:\actions-runner-m0rFq_work_tool\go\1.23.6\x64' -> 'D:\actions-runner-m0rFq_work_tool\go\1.23.6\x64'

But at least in my case it doesn't happen the first time, it happens on the second time when the file is already there.

I was actually able to make this error stop happening by just deleting the entire _work\_tool|go directory with this command:

      - name: Cleanup Workdir to workaround a setup-go bug
        # The bug mentioned above causes setup-go to fail downloading
        # Golang because "the file already exists", but disabling
        # cache doesn't fix it, so we'll just delete it manually.
        run: |
          if (Test-Path "${{ github.workspace }}\..\..\_tool\go") {
            Remove-Item -Path "${{ github.workspace }}\..\..\_tool\go" -Recurse -Force;
          }

But then I don't have the cache which means the Windows CI is taking a long time to finish, as it has to download and install Golang everytime.

Hi there 👋,
Thank you for your report. I have attempted to reproduce the issue on my end but was unable to do so.
Could you please try setting the environment variable AGENT_ISSELFHOSTED=1 in your workflow?

on:
...

env:
  AGENT_ISSELFHOSTED: 1

[xiaost]

Thanks @priyagupta108 , it works now. is the env var required for self-hosted runners? didn't know.

we're testing self-hosted windows. Didn't see this err on Linux before.

By the way, I almost forgot to answer, adding AGENT_ISSELFHOSTED=1 also fixed the issue for me.
