"Waited for * || true but it wasn't there " each time I run apt
This means that you somehow screwed up your configuration scripts, the reason why is happening is because DPkg::Pre-Install-Pkgs {"/usr/sbin/dpkg-preconfigure --apt || true";}; doesn't exist in your scripts so you may have to create it:
sudo sh -c "echo 'DPkg::Pre-Install-Pkgs {"/usr/sbin/dpkg-preconfigure --apt || true";};' >> /etc/apt/apt.conf.d/70debconf"
Then try again.
