之前我曾使用过：
sudo apt-get remove samba
我以为它会删除 samba。但它开始卸载我的所有应用程序，包括 libreoffice、texteditor、java 插件软件更新管理器等。
现在我收到更新命令的错误
$ sudo apt-get update

E: Some index files failed to download. They have been ignored, or old ones used instead.
此外，在尝试安装任何应用程序时，我收到错误，在本例中是安装 vim:-
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package vim-gnome is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'vim-gnome' has no installation candidate
任何帮助都值得感激。谢谢
答案1
-5 - No address associated with hostname
发生此错误主要是因为/etc/apt/sources.list文件中的主机名无效或拼写错误。因此，请尝试以下命令，
sudo rm /etc/apt/sources.list
sudo cp /etc/apt/sources.list.save /etc/apt/sources.list
sudo apt-get update
笔记：在运行上述命令之前，请检查/etc/apt/sources.list.save文件。如果文件不存在，则运行，
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
sudo touch /etc/apt/sources.list
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse"
并在软件和更新中启用其他软件存储库。最后运行，
sudo apt-get update
vim-gnome通过运行安装包，
sudo apt-get install vim-gnome
