Re: [gentoo-user] Digest errors in an overlay, but only in one box

[Alan McKinnon <alan.mckinnon@gmail.com>]

That overlay hasn't been manifested properly, the checksums and file
sizes don't match. You have two options:

redigest every ebuild in the entire overlay
resync and hope it's fixed (maybe report a bug)

Just to confirm, this is vapier's overlay you are using? Not niifaq?

I recall manifest problems with niifaq overlay a while ago, but can't
recall issues with vapier's. It isn't the portage tree though, so I
imagine it can be easy to forget the manifest step when committing files.

What I can't explain is why one pc is happy using the overlay files and
the other not. AFAIK portage doesn't allow digest checks to be disabled.
