我已将我的电脑从 Ubuntu 13.10 更新至 Ubuntu 14.04。
听说Ubuntu 14.04不包含Python2，但是我的Ubuntu 14.04系统仍然安装有Python 2。
我可以从我的电脑中删除 Python 2.7.6 吗？当然，我知道有些软件可能依赖于 Python2。
答案1
- 14.04 确实有 python 2。
- 如果不删除所有依赖于 python 2 的包，您就无法删除 python 2。这个比例可能超过 50%。

假设你删除了 python2.7。这将恢复桌面：
sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
