upgrade problem: unmet dependencies

new issue via: #256

pop-upgrade:
Installed: 1.0.0164210650021.04788fc60
Candidate: 1.0.0164210650021.04788fc60

#244 included fixes for ppp/libnm0 dependency issues. The version including that fix, 788fc60, was finally released on 21.04 today (it was released on 20.04 and 18.04 last week.) Closing this issue & any new occurrences will have to be triaged separately.

That's great, but how do people install it?

When attempting update I get:

The following packages have unmet dependencies:
network-manager: Depends: libnm0 (= 1.30.0-1ubuntu3) but 1.32.12-0ubuntu1 is installed
Breaks: ppp (>= 2.4.7-3~) but 2.4.9-1+1ubuntu1 is installed
network-manager-pptp: Depends: ppp (< 2.4.7-3~) but 2.4.9-1+1ubuntu1 is installed

When attempting to download the upgrade I get:

Please run the six commands suggested in your screenshot, copy/paste the complete terminal output into a text file, and attach it to a comment so we can see what sources are currently configured on your system and what state the package manager is in.

sudo apt clean
sudo apt update -m
sudo dpkg --configure -a
sudo apt install -f
sudo apt dist-upgrade
sudo apt autoremove --purge

@fluidvoice That output is not sufficient. Please provide the complete terminal output from all six commands in a text file. At the very least, we need to start with the apt update output.
