I am an Android 12 user and running AndFTP which is a great tool to connect to (almost) any Linux Box. I love it ! However, I ran into a problem with it...
I have a trouble running AndFTP v6.3 on Android 12 connecting to my Linux Server at Home.
I've recently upgraded my Linux Server to Ubuntu 22.04.1 (OpenSSH_8.9p1 Ubuntu-3, OpenSSL 3.0.2) and AndFTP does not connect anymore using the PubKey method.
auth.log on the server throws the following:
Code: Select all
sshd[249451]: userauth_pubkey: key type ssh-rsa not in PubkeyAcceptedAlgorithms [preauth]
All of the above use another more sophisticated mechanism, not just plain "ssh-rsa".
The only one that seems to have a trouble authenticating is AndFTP.
From what I understand, OpenSSH has put some security restrictions in place in order not to allow weak algorithms to be used.
I assume AndFTP needs a key upgrade procedure or something like that...
If anyone can help, please... otherwise, I must change AndFTP to other SFTP Client.
