Unmet Dependencies: gnome-settings-daemon

[Bruce Zannetti]

I get the following message from Software Updater:

The Package System is Broken
Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
Transaction failed: The package system is broken
 The following packages have unmet dependencies:

gnome-settings-daemon: Depends: libgudev-1.0-0 (>= 146) but 1:232-2 is installed
                       Depends: libnspr4 (>= 2:4.9-2~) but 2:4.18-1ubuntu1 is installed
                       Depends: libnss3 (>= 2:3.13.4-2~) but 2:3.35-2ubuntu2 is installed
                       Depends: libxi6 (>= 2:1.2.99.4) but 2:1.7.9-1 is installed
                       Depends: gnome-settings-daemon-schemas (= 3.28.1-0ubuntu1.1) but 3.28.1-0ubuntu1 is installed

I do not believe I am using third party repositories. How can I fix my system?

Thank you

If you reboot after receiving this error you will be unable to get back into the system. Boot up will hang at "Started Update UTMP about System Runlevel Changes. Alt-F2 allows you to switch to login prompt. However, attempts to purge gnome and related dependencies or perform any updates fail.

[Jason Trupp (jtrupp)]

Found the following two entries had been added to /etc/apt/sources.list following automatic updates.
deb [trusted=yes] http://ftp.us.debian.org/debian experimental main
deb [trusted=yes] http://ftp.us.debian.org/debian sid main

Commented them out and performed apt update. Then purged the following packages:
apt purge gnome-settings-daemon gdm3 gnome-control-center gnome-initial-setup gnome-power-manager gnome-shell uatter ubuntu-desktop ubuntu-session

This removed these packages, then reinstalled all pre-existing packages.

Reboot returned system to normal functionality.

Unfortunately I don't even have the entries that jtrupp mentioned in his post. My system is still broken. Funny thing is, it's a fresh install, therefore I have no software to work with...
