我的 ubuntu 软件中心无法正常工作，我试图修复它。我运行了以下一系列命令：
sudo apt-get update
这次失败了，结果如下

然后我运行了这些命令
sudo apt-get autoclean
sudo apt-get clean
当我运行该命令时sudo apt-get autoremove，我得到了以下结果：
"Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run `'apt-get -f install'` to correct these.
The following packages have unmet dependencies:
ubuntu-minimal : Depends: resolvconf
E: Unmet dependencies. Try using -f."
那么我应该强制卸载ubuntu-minimal：依赖：resolvconf
答案1
我倾向于不使用/信任，sudo autoremove因为我发现当我查看不再需要的软件包时，我已经看到了我的整个桌面（当使用 MATE 桌面时），并且有删除我实际上需要的依赖项的经历，并且因此不得不重新安装一些系统，当您发出该命令时，请务必查看它正在删除哪些软件包，因为它甚至可能删除了存储库 gpg 密钥，并且现在 install -f 不起作用，因为系统不会从不受信任的存储库下载。
这正是我使用自动删除时所经历的类型。
答案2
不，你的方法错了。你应该使用 进行安装resolvconf。sudo apt-get install resolvconf删除ubuntu-minimal会导致你的系统无法启动。
