Raspberry Pi Stack Exchange is a question and answer site for users and developers of hardware and software for Raspberry Pi. It's 100% free, no registration required.

I set up my Pi, and I get output to a screen / keyboard working etc.

However, when I run raspi-config, and pick the SSH option I get

Initial ssh key generation still running. Please wait and try again.

I left the Pi on for a few hours but this didn't help.

I tried bashing on the keyboard for a while as I assume this is due to insufficient entropy.

Is there a way to fix this??

Can you just generate the keys manually? –  Jivings Jul 27 '12 at 8:37

The advice in the Raspberry Pi forum thread (rm /var/log/regen_ssh_keys.log) got the raspi-config to make it look like it had worked, but the host keys weren't generated. I fixed this by doing

sudo rm /etc/ssh/ssh_host*
sudo ssh-keygen -A

the rm was needed as otherwise ssh-keygen was seeing the 0 length files as valid keys
