Hello @matthewhughes-uw , thank you for the input. We are starting to investigate the problem. |
do you have any updates around this to share? |

The issue seems to be caused by the setup-go being confused about the difference in "Go" version and the newly introduced "Toolchain" version.

@matthewhughes-uw That makes sense. What I don't understand is why Go on the second download defaults back from downloading 1.21.6 to instead getting 1.21.1 again. Because if this didn't happen, then there would be no cache problem. How I solved it for now is to upgrade using Then the caching issue does not appear. |

One way of avoiding this could be if You could do your own toolchain version parsing in an earlier step, and set an env var or something: |
`go version` is run before downloading the cache, but if this is run
with a version of `go` that triggers a Toolchain download[1], e.g. if
the installed Go is 1.20.0 but `go.mod` has a toolchain directive
`go1.20.1` then a toolchain is downloaded to e.g.
`$GOMODCACHE/golang.org/toolchain@v0.0.1-go1.21.1.linux-amd64`, if this
file already exists in the cache (e.g. this is the second run of this
action we not cache invalidation) then the cache download will try and
overwrite these files resulting in noisy errors like:
/usr/bin/tar: ../../../go/pkg/mod/golang.org/toolchain@v0.0.1-go1.21.6.linux-amd64/lib/time/mkzip.go: Cannot open: File exists
Instead, force `go` to use the local toolchain (i.e. the one the one
that shipped with the go command being run) via setting the
`GOTOOLCHAIN` environment variable[1]:
> When GOTOOLCHAIN is set to local, the go command always runs the
bundled Go toolchain.

For those finding this issue, the current workaround is to just ensure that your // go.mod
go 1.22.2# workflows/ci.yml
- uses: actions/setup-go@v5
with:
go-version: 1.22.2 |
You could also set the - name: Configure env for toolchain ignore

Description:
When the version of Go in the
godirective ofgo.modis different from the version in thetoolchaindirective there is a cache conflict which causes errors on cache extraction.Note: I think this is related to, but different from #403 since that appears to be covering the situation where some other tool is also working on the cache, but this issue is purely for the action running on a hosted runner without any additional changes to the environment etc.
