Problem

I upgraded ssh and now when I try to pubkey in it demands a password. In /var/log/auth.log, I find lines to the effect of:

userauth_pubkey: key type ssh-rsa not in PubkeyAcceptedAlgorithms

Solution

The "correct" solution is to regenerate your pubkeys with the latest version of putty's key generator.

If you can't or don't want to do that, you can hack:

In /etc/ssh/sshd_config, find:

PubkeyAuthentication yes

...and below it add

PubkeyAcceptedKeyTypes=+ssh-rsa

...and restart sshd.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
