我最近做过
sudo rm -rf /var/lib/apt/lists/*
sudo rm /etc/apt/sources.list
后来我去了
sudo -i software-properties-gtk
然后选中规范复选框，
sudo apt-get update 我执行的这个命令。
谁能帮我在我的 ubuntu 上安装 apache！

这通常发生在您在 apt 中混合使用不同的存储库时。有时来自不同存储库的依赖项不匹配，您就会遇到这种情况。添加 ppa 存储库时，最好确保您添加的是与您的 ubuntu 版本兼容的正确存储库。混合不同 ubuntu 版本甚至不同发行版（如 debian/mint）的存储库可能会有效，但总有可能出现问题。
