The action would require the installation of packages from not authenticated sources.

Hello everyone :)

I have just installed the ppa for the Wine.
I try to update my machine from the new ppa, but I get the error :

"The action would require the installation of packages from not authenticated sources."

I looked over the internet and I found that all I need to do is go to the update manager > Settings > Ubuntu Software and check the Source code checkbox.

It then asks me to [Authenticate] which I do, but then it DOES NOT check the check box.. So when I try to update it produces the same error.

Does anyone know if there is a way around it?
or a way to fix this?

Thank you all in advance.

You can do an apt-get update to get around it for now. Its a known issue.

Thank you for your answer !!

I did an update as you say, and rerun the Update manager.
It is now in the process of downloading and installing...


Thank you :-)
Issue is solved...

No problem. You could also have run:

sudo apt-get update && sudo apt-get upgrade
