helmfile deps is failing with Chart.lock: no such file or directory with helm 3.0.2

[Nitive]

helmfile deps is failing with Chart.lock: no such file or directory with helm 3.0.2.
It happens because helmfile tries to access Chart.lock which is not there in 3.0.2.
The behavior was changes in helm/helm#7009 and now charts without apiVersion: v2 are treated as helm 2 carts and generate requirements.lock instead

Error:

in ./helmfile.yaml: unable to update deps: unable to resolve 1 deps: open /var/folders/k_/361cq75j2sgf6dxm6625422m0000gn/T/79305915 5/Chart.lock: no such file or directory

@Nitive Thanks a lot for the detailed report!

This should be fixed on the helmfile side.

@Nitive I've fixed this in #1056 which is included since v0.98.1.

The example repository did help me a lot for reproducing the problem and testing the fix.

Thanks again for your support!
