I'm new to Linux. I just dual booted Ubuntu 16.04 on a Windows 10 computer. Every time I try to install anything errors having to do with update-notifier-common and flashplugin-installer. Here is an example when I tried to install chrome:

Setting up update-notifier-common (3.168.5) ...
Traceback (most recent call last):

dpkg: dependency problems prevent configuration of flashplugin-installer:
flashplugin-installer depends on update-notifier-common (>= 0.119ubuntu2); however:
Package update-notifier-common is not configured yet.

dpkg: error processing package flashplugin-installer (--configure):

No apport report written because the error message indicates its a follow up error from a previous failure.

Setting up chromium-browser-l10n (62.0.3202.94-0ubuntu0.16.04.1317) ...
Errors were encountered while processing:
update-notifier-common
flashplugin-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)

What does this error mean and how do I fix it?

Had the same problem and since i have installed alternative python version(3.6), and default version was(3.5), my solution was to update-alternatives --config python3 to previous version just for the update .

hope it will help for others if they oncounter same problem.
