一、报错详情
事情是这样的，我准备在Ubuntu 16.10下安装wxPython。依据官方文档，我使用的命令是：
sudo apt-get install python-wxgtk2.8
但是却出现了下面的报错，如图所示：
出错信息为：
Reading package list... Done
Building dependency tree
Reading state information... Done
Package 'python-wxgtk2.8' is not available, but is referred to another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source.
E: Package 'python-wxgtk2.8' has no installation candidate
二、解决办法
报错的原因是python-wxgtk2.8包太旧了。可以安装python-wxgtk3.0包来代替。使用以下命令，即可完美解决。
sudo apt-get install wxgtk3.0
