Here is a snippet of the issue: ... debug2: input_userauth_request: try method publickey [preauth] debug2: userauth_pubkey: valid user user-xx attempting public key ssh-rsa rsa-data-xx [preauth] debug3: userauth_pubkey: have ssh-rsa signature for RSA SHA256:sha-data-xx [preauth] debug3: mm_key_allowed entering [preauth] debug3: mm_request_send entering: type 22 [preauth] debug3: mm_key_allowed: waiting for MONITOR_ANS_KEYALLOWED [preauth] debug3: mm_request_receive_expect entering: type 23 [preauth] debug3: mm_request_receive entering [preauth] debug3: mm_request_receive entering debug3: monitor_read: checking request 22 debug3: mm_answer_keyallowed entering debug3: mm_answer_keyallowed: key_from_blob: 0x60008fcf0 debug1: temporarily_use_uid: 1074753138/1073742337 (e=18/18) seteuid 1074753138: No such device or address debug1: do_cleanup debug1: Killing privsep child 302
