我是 ubuntu 新手，所以我无法理解到底该怎么用它
答案1
尝试使用以下命令修复软件包
sudo dpkg --configure -a
sudo apt-get clean
sudo apt-get update
更新：试试这个sudo apt-get -f install
APT 将尝试下载并安装缺失的软件包以解决依赖关系
你看到了吗问题
答案2
尝试这个：
sudo apt-get -f 更新
更新：
我的错！我本想让你尝试一下这个：sudo apt-get -f install
这个想法是让apt-get我们有机会尝试修复系统（如果可能的话）。但看起来，您已经尝试过了，但问题并没有解决。启用了哪些存储库？
另外，您是否尝试过删除有问题的软件包？我会尝试这个：
sudo apt-get purge libgnutls-openssl27:amd64
