The exact command to reproduce the issue:

The full output of the command that failed:

The operating system version:
Windows 7 x64

I think it is related to
https://github.com/kubernetes/minikube/blob/cbda04cf6bbe65e987ae52bb393c10099ab62014/pkg/minikube/cruntime/docker.go#L278

The command is generated with windows filepath.Dir and filepath.Base whereas it is executed in the VM so with linux path separators

Wonder how this one passed the integration tests (on Windows), but the fallback should be working

i.e. minikube should still be working, after "falling back to caching images"

[cvila84]

I confirm the fallback works but it takes time as it first downloads 500M for nothing :)

@cvila84 thank you very much reporting this issue ! that is defentiy a bug !

shamefully our windows integration tests are broken, we have a WIP PR to add windows docker test for github actions.

I will make sure this bug is fixed as soon as possible.

@afbjorklund did not mean to be rude with my comment, I'm actually happy it still works !
@medyagh many thanks !

Sorry, I just meant it was sad that it failed in Windows - too few github reaction icons to click I suppose...

We need to get Windows CI back

Failing for me too:
