I have an Ubuntu 18.04.2 LTS (upgraded from Ubuntu 16.04, 6 months ago).
Last week, I ran sudo apt upgrade and encountered the following error due to libpython3.7:
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
I tried some commands found on stackexchange for a similar problem: sudo apt --fix-broken install, sudo dpkg --configure -a, sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade -f, but nothing works:
