Yeah. I've done this. It was stupid.
I did not know it's going to take its dependencies with itself, only wanted to install python 2 and 3 from scratch (because of this problem: https://askubuntu.com/questions/897355/how-to-change-default-idle-for-python).
Now, I can still use my terminal, checked these answers:

However after running sudo apt-get install ubuntu-desktop I get these errors:

Every apt-get install command throws this.
Is there a way to restore these dependencies?
Hallelujah.
sudo apt-get install --reinstall python python-chardet python-colorama python-distlib python-django python-django-tables2 python-six python-html5lib python-lxml python-minimal python-pkg-resources python-setuptools python-urllib3 python-requests python-pip python-virtualenv
sudo apt-get install --reinstall python-dnspython
sudo apt autoremove
sudo apt-get -f install
After a whole day of adventures in the deepest pits of internet, these commands worked for me.
python-dnspython and samba was still missing after the first command, --reinstall python-dnspython pulled samba in as well. Autoremove removed the needless dependencies.
Naturally some of these could be quite redundant but I was just following some long lost forum posts all over the place and what matters is that it worked.
