dep ensure freeze when trying to connect to no longer existing repo #1605
Description
My project use github.com/tj/go-debug which used to exist and can be dep ensure just fine before. But when I try to dep ensure again, it just freeze with no indication of what happen, is it still running or trying or just freezed. I have to check htop to see ssh git@github.com git-upload-pack '/tj/go-debug' is running constantly because this repository is not there anymore.
I propose that there should be some mechanism to determine the existence of repo first before trying to do anything else.
