我正在尝试升级我的系统但是 python3 正在破坏该过程：
sudo apt upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
python3 : PreDepends: python3-minimal (= 3.5.1-3) but 3.5.1-4 is installed
Depends: libpython3-stdlib (= 3.5.1-3) but 3.5.1-4 is installed
E: Unmet dependencies. Try using -f.
因此我使用 -f 重新运行并得到：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Correcting dependencies... Done
Calculating upgrade... Done
The following packages will be upgraded:
python3 python3-distupgrade ubuntu-release-upgrader-core ubuntu-release-upgrader-gtk

sudo apt purge -f python3修复了这个问题，系统仍然有python 2.7和3.5
