Low Description
Issue Summary
SCP Task will fail if the SSH private key is of type ed25519
Steps to Reproduce
- Create an ed25519 SSH keypair using ssh-keygen or putty-keygen
- Add the equivalent public key to the target SSH host authorized_keys file
- In Bamboo, use an SCP or SSH task to connect to the SSH host
- Run the plan/deployment
Expected Results
The SSH connection should succeed
Actual Results
Build fails with the below exception

Workarounds
- On the SCP/SSH Task use a different type of SSH private key such as RSA
- Use a Script Task with proper "ssh" or "scp" commands – This will require setting the authentication and key exchange manually on the Server and Agents
