Cannot log in as vsedach at after added SSH key to Gitlab

I still cannot connect - thanks for the heads up on the Debian
distribution issue. There might be two problems: 1.
.ssh/authorized_keys2 is still there and still trashed 2. old OpenSSH
version that does not support ED25519 keys.

I think the problem was caused because I had ControlMaster on in the SSH
config on the machine I was using - I trashed the authorized_keys2 file
when trying to add the new SSH key (there was probably a newline missing
at the end) and I did not notice until the ControlMaster connection

If you remove vsedach/.ssh/authorized_keys2 and put my new RSA key
(attached) in .ssh/authorized_keys I should be able to get back in.

Thank you!
