![Ubuntu 14.10 服务器启动](https://linux22.com/image/977240/Ubuntu%2014.10%20%E6%9C%8D%E5%8A%A1%E5%99%A8%E5%90%AF%E5%8A%A8.png)
我在运行 14.04 Server 的硬件上只安装了 OpenSSH 服务器。除了启动时要经过的检查页面之外,我认为它应该能够识别 USB 键盘的滚动锁定,但事实并非如此。
一切似乎都很好,直到我登录并得到:
[305.760849] system-logind[1419]: Failed to start unit [email protected]:
Unknown unit: [email protected]
[305.761004] system-logind[1419]: Failed to start user services:
Unknown unit: [email protected]
这两个错误是否与 OpenSSH 有关,因为它尚未设置,或者与其他东西有关?
我尝试搜索系统和 Ubuntu 上的手册和帮助文件,但没有成功。
答案1
为了挽回我的声誉,我做了更多的研究,并尝试了一些方法。在做了以下操作后,我不再收到错误消息,我的服务器似乎运行正常。我使用了此页面SystemdForUpstartUsers寻求指导。
我不知道它做了什么,但它似乎有效。我感觉 Upstart 和 Systemd 有冲突。强制安装 Systemd 后,Upstart 被删除了。
apt-get --force-yes install systemd-sysv ubuntu-standard
update-initramfs -u
这是我的输出:

答案2
我在相对较新安装的 ubuntu 15.10 上也遇到了这个问题,上面的答案说这为我解决了这个问题
sudo apt-get install systemd-sysv
我有与上述相同的 dmesg,此外我的症状包括无法从挂起状态启动,这迫使我每次都进行冷启动
答案3
我试过了,它有效
do-release-upgrade -d
您将使用“-d”开关进入开发版本。
对于这个特定的服务器,我一开始使用的是 14.04,然后执行了“do-release-upgrade”,将我升级到了 14.10。这时我开始收到同样的错误消息。所以我发现更新至 Ubuntu 14.10 后...并决定尝试一下。然后我升级到了版本 15。
