如何在16.04中删除Python 2？
Ubuntu在16.04中放弃了Python 2 。 它仍然在升级后安装（它不是“过时的软件包”的一部分）。
是否有一种干净的方式以干净的方式删除Python 2 及其所有依赖项 （以完全摆脱它）？
是一种apt purge方式吗？
root@ubuntu ~# apt purge python2.7 Reading package lists... Done Building dependency tree Reading state information... Done The following package was automatically installed and is no longer required: libnss-ldap Use 'apt autoremove' to remove it.

After this operation, 58.4 MB disk space will be freed.
由于仍有很多依赖于Python2的软件包（如Samba和VirtualBox），因此在继续使用之前，您应该仔细查看apt要删除的软件包。
使用
sudo apt purge python2.7-minimal
完全删除Python2以及依赖它的所有东西。
