I have two computers. They both have Xubuntu 15.10. I upgraded the one comoputer (which is 64 bit) but the other computer (which is 32 bit) won't upgrade.
I go to the Software Updater in the Applications Menu. I open it. It searches for updates. It gives me a window offering the 16.04LTS upgrade. I click on the "upgrade" button. It gives me the password authentication window. I put my password in and click on "authenticate" button. And nothing happens. I've done it three times with the same results.
I Googled around and found (see attachment) this from this site:

But I'm not familiar with this site. Is that (what's circled) what I need to do? Something else? Thanks.
