安装 python 3.4 后遇到了一些问题，所以我想回到 2.7。所以我彻底删除了 python...
现在当我运行这个命令时：
sudo apt-get install python(tried all versions here)
我刚刚收到一堆错误：
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
apport : Depends: python3 but it is not going to be installed
Depends: python3-apport (>= 2.14.1-0ubuntu3.15) but it is not going to be installed
Depends: python3-gi but it is not going to be installed
lsb-release : Depends: python3 but it is not going to be installed
Depends: python3:any (>= 3.3.2-2~)
sessioninstaller : Depends: aptdaemon (>= 0.30) but it is not going to be installed
software-center : Depends: aptdaemon (>= 0.40) but it is not going to be installed
Depends: oneconf (>= 0.2.6) but it is not going to be installed
Recommends: update-notifier but it is not going to be installed
Recommends: software-properties-gtk but it is not going to be installed
software-center-aptdaemon-plugins : Depends: python3-gi but it is not going to be installed
xdiagnose : Depends: python3:any (>= 3.3.2-2~)
Depends: python3-gi (>= 3.2.0-3) but it is not going to be installed
Depends: python3-apport but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
所以我尝试了：
sudo apt-get -f install

所以我现在不确定该怎么做...关于如何解决这个问题有什么建议吗？
答案1
下载并安装并强制安装python-minimal，pyclean不在您的系统上
cd
apt-get download python-minimal
sudo dpkg -i --force-all python-minimal_2.7.5-5ubuntu3_amd64.deb
sudo apt-get install -f
