Cannot ssh to AWS server when upgrade to macOS Sonoma version

When I try to login into AWS server from my MacBook Pro we got the error message below

# ssh -p 22 -i /Users/user_name/.ssh/id_ed25519 ubuntu@domain_name.com

Load key "/Users/user_name/.ssh/id_ed25519": invalid format

ubuntu@domain_namecom: Permission denied (publickey)

My colleague still in the macOS Ventura 13.5.2, which enables us to login into the AWS server via SSH.

In addition, the problem persists with all servers, not only with those aws... we have local server with ubuntu lts server version

I had a similar issue. tried many tips, but in the end it helped to:

ssh-add ~/.ssh/bitbucket_key

the key is added this way to the agent.

Suddenly it worked...

Hope this helps.

Have you tried what's suggested at the link below? It worked for me on both Ventura and Sonoma. Just make sure you add the two lines in /etc/ssh/ssh_config, NOT in /etc/ssh/sshd_config.

In case anyone else is having this issue, adding the algorithm properties to /etc/ssh/ssh_config did not work for me but adding a config file with the algorithm properties to my local .ssh directory did.
