意外从 Ubuntu 18.04 卸载了“apt”。我该如何重新安装它?

我意外删除了 apt-get,现在重新安装它时遇到了问题。

这是我所做的

dpkg -r apt (uninstalled apt-get)

我尝试下载 apt.deb 文件并重新安装

sudo dpkg -i apt_1.2.32ubuntu0.1_amd64.deb

它给了我这个错误:

Selecting previously unselected package aptitude:amd64.
(Reading database ... 200534 files and directories currently installed.)
Preparing to unpack aptitude_0.8.10-6ubuntu1_amd64.deb ...

 aptitude:amd64 depends on libsigc++-2.0-0v5 (>= 2.8.0).
 aptitude:amd64 depends on libxapian30.

dpkg: error processing package aptitude:amd64 (--install):

Errors were encountered while processing:

然后我尝试了这个:

sudo dpkg -i --force-all apt_1.2.32ubuntu0.1_amd64.deb

它给了我这个输出:

现在当我尝试使用

sudo apt-get update 

它给了我这个:

您正在尝试安装 Ubuntu 16.04 版本apt,而不是 Ubuntu 18.04 版本apt

查看此页面apt1.2.32ubuntu0.1)。请注意,页面中 URL 的面包屑导航为:

» Ubuntu » 软件包 » xenial (16.04LTS) » admin » apt

这显然是 Ubuntu 16.04 版本。但你运行的是 Ubuntu 18.04。因此你需要获取apt1.6.12ubuntu0.1)可以是找到这里。再次查看页面中 URL 的面包屑导航:

» Ubuntu » 软件包 » bionic (18.04LTS) » admin » apt

下载它直接从这里然后运行这个命令:

sudo dpkg --install apt_1.6.12ubuntu0.1_amd64.deb

你应该坚强。
