Environment

Situation

Building images using SUSE Manager Server and the Build Host fails.  The following error messages can be in found in the /var/log/rhn_web_ui.log file:
Warning: Permanently added 'some.hostname,some.ip.address' (ECDSA) to the list of known hosts.
Permission denied, please try again.

Disconnected from some.ip.address port 22
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: unexplained error (code 255) at io.c(228) [Receiver=3.2.3]
Also, in /var/log/messages on the SUSE Manager Build Host system sshd reports errors:

2024-01-15T09:23:12.502182+01:00 hostname sshd[14910]: error: maximum authentication attempts exceeded for root from some.ip.address port 57036 ssh2 [preauth]
2024-01-15T09:23:12.502261+01:00 hostname sshd[14910]: Disconnecting authenticating user root some.ip.address port 57036: Too many authentication failures [preauth]

Resolution

Apply the highstate from the SUSE Manager Server against the Build Host system.

Cause

On the Build Host system, the /root/.ssh/authorized_keys file is missing the public key from the SUSE Manager server (/srv/susemanager/salt/salt_ssh/mgr_ssh_id.pub) which is causing rsync over ssh to fail.
