sign_and_send_pubkey: signing failed for ED25519 "cardno:XXXX" from agent: agent refused operation #1404

Comment

I'm using a Nitrokey Start for storing my SSH key. I recently switched from RSA to ED25519 on this key.

Working with GitLab, this works fine.

But when I try to push to Codeberg, I get the error:

sign_and_send_pubkey: signing failed for ED25519 "cardno:XXX" from agent: agent refused operation

I'm really stunned by this, because it works well with GitLab, so I'm unsure whether this is an issue with Codeberg or my GPG/SSH/Nitrokey firmware.

Have you updated your ~/.ssh/config to use the new key for codeberg.org? Also do you have your new SSH key configured at https://codeberg.org/user/settings/keys?

I've no entry for codeberg.org anywhere in my .ssh folder and added the key correctly to codeberg.org/user/settings/keys

Alright in that case could you executing the following command and post the output? The answer is likely remains in the debug logs..

ssh -vvvT git@codeberg.org
