The two important lines from the log you posted are:

/var/lib/dpkg/info/gedit.prerm: 12: /var/lib/dpkg/info/gedit.prerm: py3clean: not found

and:

/var/lib/dpkg/info/gedit.postinst: 32: /var/lib/dpkg/info/gedit.postinst: py3compile: not found

They tell us that you're missing py3clean and py3compile, both of which are part of a Python install (specifically, Python 3). Your Python is broken.

There are a couple of things you can do to fix this. Try running

apt-get -f install

and/or

dpkg --configure -a

as root. Both of these will try to find and fix broken dependencies. If they don't work (and they might well not -- they're useful commands to try, but not panaceas), try the steps given by various answers to this question.
