The following packages have been unpacked but not yet configured.
They must be configured using dpkg --configure or the configure
menu option in dselect for them to work:
alacarte easy GNOME menu editing tool

The following packages are only half configured, probably due to problems
configuring them the first time. The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:
python-gi Python 2.x bindings for gobject-introspection libraries
python-opencv Python bindings for the computer vision library

where it repeatedly appears

/var/lib/dpkg/info/apport.postinst: 13: /var/lib/dpkg/info/apport.postinst: pycompile: not found

Solution:

So, it’s probably a problem with python and apport

Then, Google related information, the result is that apport and python need to be reinstalled, related links: package-management and dpkg returned an error code, related names are as follows:

reinstall python:

sudo apt-get -m –reinstall install python python-minimal dh-python

sudo apt-get -f install

reinstall apport:

sudo apt-get update

sudo apt-get install –reinstall apport

sudo apt-get -f install

sudo apt-get dist-upgrade

Outcome:
