Error when trying to `go get` dependencies re: google cloud

[zenhack]

$ make update-deps
# Update the versions of these in go.mod:
go get capnproto.org/go/capnp/v3
go: loading module retractions for cloud.google.com/go/compute@v0.1.0: version "v1.20.0" invalid: unknown revision refs/tags/compute/v1.20.0
make: *** [Makefile:7: update-deps] Error 1

Need to investigate further.
