I finally was able to solve this. It turns out, my key was too old and thus kind of disabled as a security measure, I suppose. After creating a new key based off ED25519 and adding the corresponding public key to ~/.ssh/authorized_keys on the server, things are now working again.
Can we please do better and inform the user what's wrong instead of silently pretending to be working but dropping the unlocked key? FWIW, even now with the process working again "keychain -l" still lists nothing. I'm not 100% sure but that looks like a bug of its own. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1764044 Title: ssh-add asks about passphrases for keys already unlocked in the keychain Status in openssh package in Ubuntu: New Bug description: In the below example, on the second invocation of ssh-add I should not be prompted to enter the passphrase again after I successfully entered it on the first instance.
