Ubuntu – get Ubuntu Software on Kubuntu 16.04

I am suffering the similar problem. When I want to search for an application or install updates (however it shows number of available updates), its hanging and circling there, nothing shows. A quick fix I found is:

1) kill or end the process "gnome-software" using any tool like "System monitor" or "htop" or "pkill"

2) Open the Ubuntu sofware

3) Search for the apps or install updates.

It will work like its expected, no more hanging.

I got the same thing, just go into the terminal and run sudo su. Then, enter the software center with software-center. This worked for me on 14.04, and it should work for you, good luck, fellow Chromebook Linux user!
