我正在使用 Debian 和 Gnome 进行测试。由于某种原因，在我输入密码并按 Enter 键后，大约需要三分钟才能登录。原因可能是什么？我很想提供更多细节，但我不知道从哪里开始。
一经请求：
$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 klutt-desktop.klutt klutt-desktop
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
按需2：
$ systemd-analyze blame | head -n3
1min 25.769s ssh.service
6.764s NetworkManager-wait-online.service
612ms udisks2.service
好像是ssh。检查日志tcl
$ sudo journalctl | grep ssh

在我运行之后，后来重新启动的journalctl中的一段systemctl disable ssh.service：

geoclue和realmd似乎是候选者。
