The cache question seems unclear, how about just:

Suggested change
"Checkout failed for following targets:\n{}\nIs your "
"cache up to date?\n{}".format(
"Checkout failed for following targets:\n{}\n"
"Visit {} for more info.".format(

"Visit {} for more info." sounds like holding a user hostage. We do need better exception message, which can be done by making _fetch and _checkout collaborate with each other, but making CheckoutError message generic is not a solution, it only adds confusion.

@skshetry Good point. Maybe for a lack of better message (because a more advanced approach is needed), let's just append "Vinit {} for more info"(or someting like that) to the old message? Just in the interest of time, since the proper-proper solution will require quite a bit more effort.

@efiop I was sort of thinking the same thing myself. I updated it to that and removed the "Fixes #4316" since that issue goes deeper than this. I think other changes are unrelated to this PR at this point?

Also I should note the link is live on dvc.org now.

@efiop, yeah, that sounds good. But let's keep the issue open.
