ssh-keygen

I've currently an old SSH key uploaded on the server. The problem is I lost my ~/.ssh directory (with the original id_rsa and id_rsa.pub files). Consequently, I want to remove the old SSH key directly on the server and upload a new one. I tried the following command without success: $> ssh-add -D Is there a way to completely remove a SSH key? VonC Note that there is at least two bug report for ssh-add -d/-D not removing keys: " Debian Bug report #472477: ssh-add -D does not remove SSH key from gnome-keyring-daemon memory " " Ubuntu: ssh-add -D deleting all identities does not work. Also, why

I have the following code: ssh_key = paramiko.RSAKey.from_private_key_file(key_filename) the key looks like this: -----BEGIN OPENSSH PRIVATE KEY----- b3BlbnNzaC1rZXktdjEAAAAABG5vbmUAAAAEbm9uZQAAAAAAAAABAAABFwAAAAdzc2gtcn NhAAAAAwEAAQAAAQEAqdgmJ2AQlmvpCsDWjbpIvIrx4AwtKn2t10wmGZIN9pqcJgQpo3HD and is valid: $ ssh-keygen -l -f <mykeyfile> $ 2048 SHA256:x8jlUAObU3q2KXRtuGpxwhnGvB/ZoeD2IUqSA1OkCmI thomas@Thomas-MBP-2017 (RSA) but I get the the following error: not a valid RSA private key file This is on MacOS, Python 2.7, Paramiko 2.4.2 What am I doing wrong? For OpenSSH 7.8 up, you have to trick it
