I'm on Ubuntu 16.04 GNOME, and for a few weeks, whenever I'm running the Software Updater, I'm getting the Not all updates can be installed error:

Partial upgrade

After going for the Partial Upgrade option, pending software updates itself (if any), else I get the The software on this computer is up to date message. Whereas the Continue option gives following message:

Broken software index

Running these commands:

sudo apt install -f
sudo dpkg --configure -a
sudo apt dist-upgrade

Aren't showing any problem, yet this message pops up every time. I even tried the Synaptic Package Manager and tried to fix broken packages, but nothing happened. How to fix this problem?

[EDIT] Here's the output of sudo apt-get update && sudo apt-get upgrade:

  • Instead of apt, try apt-get, as in sudo apt-get install -f and sudo apt-get update && sudo apt-get upgrade May 10, 2017 at 0:41
  • " I even tried the Synaptic Package Manager and tried to fix broken packages, but nothing happened. " Can you expand on what "nothing happened" means? Did Synaptic show broken packages? May 10, 2017 at 1:00
  • @CharlesGreen I tried the apt-get just now, still getting the problem. @OrganicMarble When I go to Edit -> Fix Broken Packages in Synaptic, the status bar shows Successfully fixed dependency problems message instantly.

  • When you use sudo apt-get update && sudo apt-get upgrade, can you append the output of this command to your question? May 10, 2017 at 19:22
  • @CharlesGreen done. check the edited post.

  1. Try deactivating the unsupported updates in the Software & Updates window.
  2. Go to the tap, where you can see a list of repos. Look carefully on all checked repositories. Deactivate the repos you don't know and they seems weird to you like unofficial graphic driver repos

  • Already done that, the problem persists.

  • Maybe you forgot something. Can you paste your list of repos please. Note: I had the same problem like you and I have fixed it (see my answer)

Software Updater initiated updates began causing those Partial Upgrade dialogs after I enabled the

Developer Options > Pre-release updates (artful-proposed) setting.

Those dialogs stopped after I unchecked Developer Options > Pre-released updates.
