Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 python3-aptdaemon.pkcompat : Conflicts: packagekit
                              Conflicts: packagekit:i386
E: Broken packages

I have tried to remove the conflicting packages:

nuc ➜  ~  sudo apt remove packagekit packagekit:i386

I tried spinState010's suggestion but it didn't resolve this same issue for me. What did was:

sudo apt remove python3-aptdaemon.pkcompat

So, you might give that a try instead and let us know if that worked for you.

Make sure that your important files and file system are backed up before doing a distro update. I recommend using rsync for any type of file system backups. Have you tried

sudo apt clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
