Looking at the error, send_pubkey_test: no mutual signature algorithm usually hints at a more recent OpenSSH client that no longer supports certain algorithms and hence you need to whitelist them.

You can issue:

ssh -Q PubkeyAcceptedAlgorithms

To get a list of allowed algorithms.

I took the solution from atlassian help

Add PubkeyAcceptedKeyTypes +ssh-rsa to ssh_config

Another solution is

ssh-keygen -t ed25519 -C "[email protected]"

To create a new key, add to ssh/authorized_keys and you should be good to go.

Add PubkeyAcceptedKeyTypes +ssh-rsa to your ./ssh/ssh_config

Another solution is

ssh-keygen -t ed25519 -C "[email protected]"

To create a new key, add to .ssh/authorized_keys and you should be good to go.
