我正在运行 Ubuntu 16.04 LTS。我用了sudo apt-get autoremove

如果我没记错的话，我使用了sudo apt-get dist-upgrade，但我取消了中间的过程。我收到了(Y/N)升级到最后的提示，然后输入了 N。

在此之后，我在运行时遇到了一些这样的问题 apt-get update

有趣的是，我实际上运行的是 16.04。

Distributor ID: Ubuntu
Description:    Ubuntu 16.04.4 LTS
Release:    16.04
Codename:   xenial

但不知何故 apt-get 寻找artful包而不是那些用于xenial.

编辑：这就是我的/etc/apt/sources.list样子

我到处都用 xenial 替换了 artful，问题似乎已经解决了。
