After an upgrade of desktop and server (both) to Ubuntu 11.10, periodically the desktop is unable to perform publickey authentication with the server (-v option reveals nothing of evidently use). Using the same key from pre-11.10 and Windows partitions is successful.

"Any ideas what gives?" Thanks.

This question came from our site for users of Linux, FreeBSD and other Un*x-like operating systems.

NOTE: I'm getting comment notifications for the Q above but it looks like they're not being posted. Bug in the migration of the question?

In my case, this was some kind of routing error when using a domain name to ssh to the server (which was at Amazon). ssh -vvv revealed that we were being routed to another IP for some reason (I suspect AWS's internal DNS). ssh-ing to the direct IP address of the server resolved the issue.
