gpg-connect-agent password prompt gets auto filled by kitten - unable to enter password

[martin-fiedler]

Describe the bug When using normal ssh I can enter my password for nitrokey decryption, but If I use kitten ssh (which is needed or else the 'xterm-kitty': unknown terminal type error comes up) the password prompt gets auto filled by kitten.

It is also not possible to delete what ever kitten tries to pass, as it gets filled out in an endless loop.

To Reproduce Plug in a gpg based usb token (in my case Nitrokey) Run gpg-connect-agent updatestartuptty /bye Have as ssh alias kitten ssh ssh username@hostname

The kitten is not autofilling anything, it is transmistting data over the tty. I have no idea what gpg-connect-agent does. Presumably it is something you have configured ssh to use for authentication? Use the https://sw.kovidgoyal.net/kitty/kittens/ssh/#opt-kitten-ssh.askpass askpass option. Set it to ssh and you should be fine, at the cost of increased initial connection latency.
