我不小心刪除了 apt-get，現在重新安裝它時遇到問題。
這是我所做的
dpkg -r apt (uninstalled apt-get)
我嘗試下載 apt.deb 檔案並安裝回來
sudo dpkg -i apt_1.2.32ubuntu0.1_amd64.deb
它給了我這個錯誤：
Selecting previously unselected package aptitude:amd64.

然後我嘗試了這個：
sudo dpkg -i --force-all apt_1.2.32ubuntu0.1_amd64.deb
它給了我這個輸出：

現在當我嘗試使用

Ubuntu 18.04.5 LTS
答案1
您正在嘗試安裝 Ubuntu 16.04 版本apt，而不是 Ubuntu 18.04 版本apt。
查看此頁面apt（1.2.32ubuntu0.1）。請注意，頁面中 URL 的麵包屑是：
» Ubuntu » 軟體包 » xenial (16.04LTS) » admin » apt
這顯然是 Ubuntu 16.04 版本。但您執行的是 Ubuntu 18.04。所以你需要得到apt（1.6.12ubuntu0.1）這可以是在這裡找到。再次查看頁面中 URL 的麵包屑：
» Ubuntu » 軟體包 » bionic (18.04LTS) » admin » apt
下載它直接從這裡然後運行這個命令：
sudo dpkg --install apt_1.6.12ubuntu0.1_amd64.deb
而且你應該要很強。
