How to Fix ‘Requires installation of untrusted packages’ error in Ubuntu 10.10 Maverick Meerkat 65


This morning I tried to update my Ubuntu machine and got this error massage ‘Requires installation of unstrusted packages’ and couldn’t figure out why. I later found out that I was missing some GPG keys. If you find yourself in this same situation and need help with it, I’m going show you how to quickly resolve it in Ubuntu Lucid or Maverick.

 

The error screen below is what you’ll get when you try to update your system via Update  Manager.

 

untrusted_mav 

 

To fix it, go to Applications –> Accessories’ –> Terminal. and run the command below:

sudo apt-get update

untrusted_mav_1

 

Then take notes of all the numbers (keys) after ‘NO_PUBKEY’. I have underlined my missing keys in the image above.

 

To install the missing public keys, run the command below for each missing key. Replace XXXXXX with the key shown

sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com XXXXXXXXX

untrusted_mav_2

 

After that, type the command below to update your package repository with the missing key:

sudo apt-get update

untrusted_mav_4

 

Next, try updating your system again, and this time it should work.

 

untrusted_mav_3

 

Thanks for reading and please come back soon.
