Cannot remove apt package (unmet dependencies)
Problem description
It all started when I tried to install texlive 2016 following this post. I added a PPA as follows:
sudo add-apt-repository ppa:jonathonf/texlive
and then installed texlive-full. Unfortunately the installation crashed and then I decided to remove the whole package and reinstall it.
I first tried to remove texlive-full using apt-get remove, but I get the following error:
$ sudo apt-get remove texlive-full
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'texlive-full' is not installed, so not removed
You might want to run 'apt-get -f install' to correct these:

Similarly, sudo apt-get install --reinstall texlive-full fails with message E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
After all this failed, I tried:

I then ran sudo dpkg --configure -a and again sudo apt -f install, but nothing changed and dist-upgrade replays the above errors.
I tried sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade which exited with the same error messages as above.
Part 2
I could not install ppa-purge using apt, so I installed it manually by running:
mkdir ppa-purge && cd ppa-purge && wget http://mirror.pnl.gov/ubuntu/pool/universe/p/ppa-purge/ppa-purge_0.2.8+bzr56_all.deb && wget http://mirror.pnl.gov/ubuntu//pool/main/a/aptitude/aptitude_0.6.6-1ubuntu1_i386.deb && sudo dpkg -i ./*.deb
Then I removed the PPA that caused the trouble in the first place. I ran:
sudo apt-get autoremove --purge texlive*
and I got these error messages:

However, the above procedure did not resolve the problem. Here is the output of sudo apt -f install:

Just had a headache myself today with having to fix a broken kernel 4.14.36 and 4.14.37 which could not be removed due to symbolic link errors.
Referring to this Q&A: Remove broken PPA package with unknown option, but following my "cheat" method, edit the file /var/lib/dpkg/info/context.postrm and after the line:
#!/bin/sh
insert the line
exit 0
Save the file and use:
sudo apt install -f
It should run without any errors now.
