Getting "OSError: [Errno 9] Bad file descriptor" starting today

I dumped a few ipas last week and everything worked perfectly for the most part, however today, any app I try to dump results in this error

Hi! Did you read this part of the README

For SSH/SCP make sure you have your public key added to the target device's ~/.ssh/authorized_keys file.

I experienced the same problem as you, and this solved it.

do ssh connect to your device first ,all users do connect.
