do-release-upgrade fails after 18.04.1 LTS

[dragans2]

hi tux43, today I ran do-release-upgrade in Ubuntu 16 and ended in the same situation as mentioned above (same unmet dependencies).

What helped me:

1. to use sudo dpkg --remove [package-name] to remove problematic packages found via sudo dpkg --configure -a (source: https://stackoverflow.com/a/35969176/557223 ). Some packages couldn't be removed as they were dependencies of another packages.
2. to run sudo apt-get install -f (it started to working again, yay)
3. to rename org.freedesktop.systemd1.service file as mentioned above and also mentioned in https://askubuntu.com/a/838673
4. to run sudo apt-get update and dist-upgrade and autoremove
5. to finally eat some food, since I was very hungry due to solving the issue

Try renaming that file, and then fixing again:

sudo mv /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service.bak
sudo apt -f install

Hello,

I had the exact same issue on release upgrade and renaming

/usr/share/dbus-1/system-services/org.freedesktop.systemd1.service

worked like a charm, thanks for that
