[SOLVED] "Unauthorized packages" error in Ubuntu's (Ubuntu MATE xenial) Software Updater

c_t_f · 09-26-2016, 12:03 PM

As mentioned in the title, whenever I use the Ubuntu software updater I get an "unauthorized packages" error. It says this in a window without any extra details and gives me the option to change settings (none of which look like they'd help at all) and restart the update, or the "OK" button which cancels the entire update.

I'd like to know which program(s) are being problematic, how I can fix the issue, and how to prevent this from happening in the future.
Thanks in advance!

Hi...

Does the actual error message say: "Requires Installation of Untrusted Packages?" If so, take a look at the solutions here or here and see if they help.

If not, please post back with a screenshot of the actual error message you're receiving.

Hi! Thank you for the reply, and sorry for the wait!

Unfortunately neither of these solutions worked, though you were right with it saying "Requires installation of untrusted packages".
Trying the first solution gave me this output:

Quote:

They have been ignored, or old ones used instead.

Trying the second solution more or less did the same thing as I mentioned in my first post.
I also attempted the third solution mentioned on both pages (entering sudo apt-get update && sudo apt-get upgrade into the terminal), which also didn't work (it never prompted me about installing untrusted packages), and gave me this output:

Hi...

Thank you for providing the outputs, they gave me a better understanding of what's going on. The servers of two APT addresses mentioned appear to be down or no longer available.

Ok, if you would, please open the Synaptic package manager and click on "Settings" on the upper left hand corner. Then click "Repositories" from the drop down menu. After doing so, a window should come up that's called "Software & Updates." Click on the "Other Software" tab and uncheck the following entries in the white field...

http://download.opensuse.org/reposit...xUbuntu_16.04/

http://dansh.org/deb/dists/games/InRelease

http://ppa.launchpad.net/aheck/ppa/u...amd64/Packages

After doing this, make sure to allow Synaptic to update or refresh the repositories list upon closing the window. Another window should come up offering to do this. If it doesn't, run the following command in a terminal...

Code:

sudo apt-get update

Disclaimer: Be careful with these commands. Ones that are prefaced with "su" or "sudo" will essentially allow root access to your system. Mistakes could possibly damage or even destroy your OS.

Let us know how it goes.

Regards...

It worked! Thank you very much! I would have never guessed that was the issue.
