Ubuntu 16.04 将 python 从 2.7 升级到 3.6 然后再次将 2.7 设置为默认值后，终端未打开

Question

I used this tutorial to upgrade to python 3.6 since I couldn't use pip and many answers said that pip dropped the support of python 2.7. But now I can't open terminal. Some answers suggested going back to default version will help. But in update alternatives list there was no python2.7, so I installed it and set it as default but still the terminal won't open. Any help is appreciated. Thank you.

Ubuntu 16.04 is optimized for python 2.7 and python 3.5. Perhaps when you installed Python 3.6, Ubuntu's default Python setting was set to 3.6. So if you lower the python default setting to python 2.7 or python 3.5 it should work fine.
