Still relevant?

I realized it happens when the cache directory is owned by some one else. A very valid reason to die, but it shouldn't panic - it ought to print a nicer message.

Hey @ry, can i start working on this issue?

@nimish-gupta Please do! It should be a small change.

Seems to work okay now. Can this be closed?
