我将 Ubuntu 从 17.04 更新到 17.10，然后又更新到 18.04，现在我的 Python 似乎坏了。运行apt-get upgrade返回以下错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
运行apt --fix-broken install结果出现如下错误：

有人知道如何解决这个问题吗？
答案1
我不知道为什么，但python2.7指向/usr/local/bin/python2.7哪个有版本 2.7.3，而python指向/usr/bin/python2.7哪个有版本 2.7.15。
我只是重新命名了一下/usr/local/bin/python2.7，现在apt-get upgrade可以按预期工作了。
