I installed Ubuntu 16.04 and I did all available updates. When I turn on my laptop, sometimes I notice CPU working at 100% due to "fwupd" process and so I have to kill it manually to avoid getting battery discharged fast!
Is there a solution for this problem?

Ok I tested the solution I reported in my previous comment and it worked like a charm.

    There is a launchpad site here that might help you: bugs.launchpad.net/ubuntu/+source/appstream-glib/+bug/1591868

    Ok. It seems that removing and reinstalling gnome-software should fix it: 1) killall gnome-software 2) sudo killall fwupd 3) sudo apt-get update 4) sudo apt-get dist-upgrade 5) sudo apt-get autoremove gnome-software 6) sudo apt-get install gnome-software Little question: Typing dist-upgrade should upgrade Ubuntu version to 16.10 ??

    As far as I know, it doesn't upgrade your ubuntu system (don't use ubuntu as often) but I can reassure you with this post here: askubuntu.com/questions/81585/…

I had the same problem and it can be an apt-get cache problem so it's recommended to clean the cache :

  1. sudo -ic
  2. apt-get clean
  3. cd /var/lib/apt
  4. mv lists lists.old
  5. mkdir -p lists/partial
  6. apt-get clean
  7. apt-get update

or it can be a permission problem

  • sudo chown {user} /home/{user}/.cache/dconf

this solve the problem for me.
