sshd not accepting ssh-rsa key auth after update on gentoo

message: key type ssh-rsa not in PubkeyAcceptedAlgorithms

Test shows, that ssh-rsa is available:

# ssh -Q PubkeyAcceptedAlgorithms | grep rsa
# ..
# ssh-rsa
# ..

It’s a bug. Workaround: Edit your /etc/sshd/sshd_conf:

PubkeyAuthentication yes
PubkeyAcceptedKeyTypes=+ssh-rsa
