Ubuntu apt-get upgrade报错问题
在ubuntu16.04中对源进行upgrade时报错：

其中反复出现
/var/lib/dpkg/info/apport.postinst: 13: /var/lib/dpkg/info/apport.postinst: pycompile: not found
解决方法：
所以，很可能是python和apport出问题了
然后，Google相关的信息，得到的结果是apport和python需要重装，相关链接：package-management和dpkg returned an error code，相关的名令如下:
重装python:
sudo apt-get -m --reinstall install python python-minimal dh-python
sudo apt-get -f install
重装apport:
sudo apt-get update
sudo apt-get install --reinstall apport
sudo apt-get -f install
sudo apt-get dist-upgrade
结果：
ubuntu@SIFT-SYS-7048GR-TR:~$ sudo apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
