Did you forget to fetch? is generally not the solution to my problem

Bug Report

I occasionally do dvc pull and get a failure with the message "Did you forget to fetch?". In my case the cause has always been that I've forgotten to push on another machine. The message could be expanded to cover this use case.

Please provide information about your setup

Output of dvc version:

1.2.1

Additional Information (if any):

If applicable, please also provide a --verbose output of the command, eg: dvc add --verbose.

@braaannigan but you do get the warnings that particular file was not found locally and remote, right?

AFAIK, we introduced a warning mechanism (instead of throwing) to make sure we download as much as we can. pull command consists of two separate operations: fetch and checkout. The error that you are mentioning happens on checkout. I guess what we could think of doing is gathering the failed downloads and reacting to them before entering checkout since we know that it has to fail.

Would that reaction include more suggestions of what might have gone wrong?

@braaannigan
I don't think it will contain more information that is already present in log. There should be WARNING entry that data has not been downloaded. But we should be able to stop the execution before entering checkout so that there is no misguiding message in the end.
