[Bug 1630182] Re: package failed to install/upgrade something. Some dialog popped up. Any info got lost after clicking. I didn't anticipate I would have to log it by myself.

The logs that were automatically attached to your bug report include the
following errors:

Processing triggers for gnome-icon-theme (3.10.0-0ubuntu2) ...

(gtk-update-icon-cache-3.0:27256): GdkPixbuf-WARNING **: Cannot open
pixbuf loader module file '/usr/lib/x86_64-linux-gnu/gdk-
pixbuf-2.0/2.10.0/loaders.cache': No such file or directory

This likely means that your installation is broken.
Try running the command
  gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
to make things work again for the time being.
Setting up update-notifier-common (0.154.1ubuntu2) ...
Traceback (most recent call last):
  File "/usr/lib/update-notifier/package-data-downloader", line 26, in <module>
    import debian.deb822
ImportError: No module named debian.deb822

We have seen this error reported more than once, but it's not
reproducible.  I know of no way this could happen without a corrupted
installation, because update-notifier-common directly depends on python-
debian, which contains the debian.deb822 python module.  Does the file
/usr/lib/python2.7/dist-packages/debian/deb822.py exist on your system?
What does the command 'md5sum /usr/lib/update-notifier/package-data-
downloader' return?
