I get this error when I try to upgrade ubuntu

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

This was likely caused by: * Unofficial software packages not provided by Ubuntu Please use the tool 'ppa-purge' from the ppa-purge package to remove software from a Launchpad PPA and try the upgrade again.

If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.If you want to investigate this yourself the log files in '/var/log/dist-upgrade' will contain details about the upgrade. Specifically, look at 'main.log' and 'apt.log'.

I just noticed this app in my ubuntu applications called Icon Browser.

I want to know if it's legit part of Ubuntu or could it be malware using it to disguise itself of other code.

In other words if it is a part of normal ubuntu package and if not how I can remove it.

Additional Info

Here's the output of searching for the app in apt

$ apt list icon* --installed
Listing... Done

Sometimes when I boot into ubuntu it's loading icon is offset like a webpage that the css hasn't fully loaded

it froze like this then when i clicked "Enter" I got back what looked like the terminal but when I typed couldn't see any text appearing so I did a force shutdown by holding down the power button and then rebooted it.

Now it doesn't go past this point.

I want to report a bug with the default video player in Ubuntu.

Based on this instructions I need to also know the program name. On the icon it's named "Videos" but using ubuntu-bug videos returns an error that the package isn't installed. That is the name of the app.

App Visible on the background using Alt+F2 to trigger an error reporting modal. That states there's no such app with that name

Just saw this nice zombie wallpaper http://9gag.com/gag/a1bepwb and it's source https://steamcommunity.com/sharedfiles/filedetails/?id=845108672 is it possible to use it in linux? FYI: I'm very handy with the terminal :)
