<br>
I still cannot connect - thanks for the heads up on the Debian<br>
distribution issue. There might be two problems: 1.<br>
.ssh/authorized_keys2 is still there and still trashed 2. old OpenSSH<br>
version that does not support ED25519 keys.<br>
<br>
I think the problem was caused because I had ControlMaster on in the SSH<br>
config on the machine I was using - I trashed the authorized_keys2 file<br>
when trying to add the new SSH key (there was probably a newline missing<br>
at the end) and I did not notice until the ControlMaster connection<br>
expired.<br>
<br>
If you remove vsedach/.ssh/authorized_keys2 and put my new RSA key<br>
(attached) in .ssh/authorized_keys I should be able to get back in.<br>
<br>
Thank you!<br>
