Since upgrading to Kubuntu 24.04, I am prompted by a GUI requesting a password the first time I ssh to a new server (and subsequently later after a timeout, it seems).I have tried disabling kdewallet and also uninstalling ksshaskpass, and unsetting SSH_ASKPASS in the environment. It feels like some sort of keyring but I don't know what.
My keys exist in the ssh-agent (verified with ssh-add -l).For some servers, the required password is my login password rather than the actual key password. It's possible that I messed something up during the upgrade when prompted to provide a password, but I don't recall exactly.
ssh -vv shows
debug1: Will attempt key: <keyname> RSA SHA256:<shasum> explicit agentdebug1: Offering public key: <keyname> RSA SHA256:<shasum> explicit agentdebug1: Server accepts key: <keyname> RSA SHA256:<shasum> explicit agent
