我在Lubuntu 16.10计算机上将Python从2.7.12升级到3.4.2时遇到了问题。我是一个Linux菜鸟所以希望更新就像apt-get update一样简单...然后在某处读取apt-get install将删除旧版本并替换为新版本。所以我尝试了，但这就是我得到的：
$ sudo apt-get install python 3.4.2

python is already the newest version (2.7.11-2).
You might want to run 'apt-get -f install' to correct these:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
apt-get -f install没有帮助。升级到Python 3.4.2需要做什么？
答案 0 :(得分：0)
显然我刚刚被告知Python 3.4.2不适用于我的发行版
