Ubuntu-budgie 18.04 代理尝试使用公钥进行 ssh 时拒绝操作

当我尝试使用 rsa 密钥对进行 ssh 时,出现以下错误:

debug1: Next authentication method: publickey
debug1: Offering public key: RSA SHA256:2zjgjRVRDdbdfmjqip0o7M5vGXRmdH1vIvT88rrF3yE /home/home/.ssh/id_rsa
debug3: send_pubkey_test
debug3: send packet: type 50
debug2: we sent a publickey packet, wait for reply
debug3: receive packet: type 60
debug1: Server accepts key: pkalg rsa-sha2-512 blen 535
debug2: input_userauth_pk_ok: fp SHA256:2zjgjRVRDdbdfmjqip0o7M5vGXRmdH1vIvT88rrF3yE
debug3: sign_and_send_pubkey: RSA SHA256:2zjgjRVRDdbdfmjqip0o7M5vGXRmdH1vIvT88rrF3yE
sign_and_send_pubkey: signing failed: agent refused operation

如果我尝试从服务器计算机登录到其自身,则不会发生这种情况。如果我使用其他机器,就会发生这种情况。我在服务器和客户端计算机上都运行 Ubuntu Budgie。home.ssh文件夹的权限设置为700,并将authorized_keys设置为600
这是我的 ssh 服务器配置的副本(sshd_config):

#   $OpenBSD: sshd_config,v 1.101 2017/03/14 07:19:07 djm Exp
# This is the sshd server system-wide configuration file.  See

# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.

答案1

这可能是由于 ssh 密钥的权限太开放造成的。以下命令可能会修复此问题

chmod 600 .ssh/id_rsa

如果没有尝试使用命令

ssh 添加
