apt-get没有安装任何linux服务器

Question

apt-get install的任何内容都会出现以下错误

您可能希望运行'apt-get -f install'来纠正这些:
以下包具有未满足的依赖关系:
openssh-server:取决于:openssh-client(= 1:6.0p1-4)但是1:6.0p1-4 + deb7u2将被安装
E:未满足的依赖项.尝试'apt-get -f install'没有包(或指定解决方案).

如果我尝试安装apt-get -f install,则会出现以下错误

reparing to replace openssh-server 1:6.0p1-4 (using .../openssh-server_1%3a6.0p1-4+deb7u2_amd64.deb) ...

sudo apt-get update也没有完全正常工作.建议请

Answer 1

sudo apt-get update
sudo apt-get -f install
sudo apt-get install openssh-server

如果您没有以root用户身份登录(正如我所假设的那样),您应该sudo在添加/删除软件包之前放入系统.

如果这不起作用,请运行以下命令:

chattr -i /usr/bin/sshd
chattr -a /usr/bin/sshd 
sudo apt-get update
sudo apt-get -f install
sudo apt-get install openssh-server

如果这不起作用,您还可以转到/var/lib/dpkg/info并/var/cache/apt/archives删除名称接近的任何内容openssh-server.然后,运行命令:

sudo apt-get update
sudo apt-get -f install
sudo apt-get install openssh-server

pd:这是非常复杂的,所以无法访问系统意味着很多"尝试和失败":(
