network-manager dependency preventing upgrade after moving to 21.10

[IcedEagle]

How did you upgrade to 21.10? (Fresh install / Upgrade) Upgrade from 21.04

Related Application and/or Package Version (run apt policy $PACKAGE NAME):

Issue/Bug Description: After running the command to upgrade, which appeared to be successful, I then restarted as the upgrade command instructed. Upon trying to update anything, I'm now met with dependency errors I'm not sure how to resolve.

Here is the list of commands

**brian@brian-popos:~$ sudo apt upgrade**

You might want to run 'apt --fix-broken install' to correct these.
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
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

E: Sub-process /usr/bin/dpkg returned an error code (1)

I also ran dpkg --configure -a, and this is the output

brian@brian-popos:~$ sudo dpkg --configure -a
dpkg: dependency problems prevent configuration of ppp:
 network-manager (1.30.0-1ubuntu3) breaks ppp (>= 2.4.7-3~) and is installed.

Steps to reproduce (if you know): 1) Have Pop 21.04 up to date 2) Run command: sudo pop-upgrade release upgrade -f 3) Once command says it's successful, restart as instructed 4) Run sudo apt update, followed by dpkg --configure -a as the system instructed 5) dpkg failed due to dependency errors, and now my system is stuck in this state

Expected behavior: Once I restart, I can upgrade the system without issues.

Other Notes: The system About page still says I'm on 21.04, but I'd imagine that's because I wasn't able to fully update the system afterwards.

I found this older forum post describing similar behavior to what I'm seeing, but no definitive solution. Since this is a beta, I didn't want to get too far into experimenting with my system, to make sure it remains useful so it can be understood and fixed properly.

I solved this for myself by running

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

This worked for me:

sudo dpkg --force-depends -r ppp sudo dpkg --configure -a sudo apt update sudo apt --fix-broken install sudo apt dist-upgrade

@BobbyBeeblebrox had to go thru it while updating to 21.10, Thanks for the recipe.
