When trying to install packages through the software updater on Ubuntu 14.04.1 LTS I get following error:

Software Updater error

It's about these packages: Software Updates packages

I have selected following settings from where to install updates from: Software & Updates settings

I have run following commands:

sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade

sudo apt-get update gives following output:

Reading package lists... Done
W: GPG error: https://download.01.org trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A902DDA375E52366
W: Duplicate sources.list entry http://dl.google.com/linux/chrome/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-i386_Packages)

sudo apt-get upgrade gives following output:

The following packages have been kept back:
  libegl1-mesa libegl1-mesa-drivers libgbm1 libgl1-mesa-dri libgl1-mesa-glx
  libglapi-mesa libgles1-mesa libgles2-mesa libosmesa6 liboxideqt-qmlplugin

UPDATE

With question How do I deal with "unauthenticated sources" errors in the Software Center?

issueing following commands:

sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update

still gives following output:

Reading package lists... Done
W: GPG error: https://download.01.org trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A902DDA375E52366
W: Duplicate sources.list entry http://dl.google.com/linux/chrome/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-i386_Packages)

Followed the second answer:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A902DDA375E52366
sudo apt-get update

but receive following error:

W: Duplicate sources.list entry http://dl.google.com/linux/chrome/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

and apt-get update doesn't correct the problem

  • what is the output of sudo apt-get update? – g_p Jan 27 '15 at 9:10
  • @g_p I added the output. I'm guessing the GPG error might be the problem? – Noosrep Jan 27 '15 at 9:15
  • @g_p Still doesn't work, I edited the question – Noosrep Jan 27 '15 at 10:46
  • As you don't have GPG error now, You would not get the warning you were getting earlier. For Duplicate sources.list warning see this post. – g_p Jan 27 '15 at 10:56

You could run:

sudo apt-get update && sudo apt-get dist-upgrade
  • Voilà! Worked for me at first time! – GFPF May 24 '18 at 16:17

To fix the duplicate entry in your sources.list file:

Open it in an editor with root/sudo rights e.g:

sudo nano /etc/apt/sources.list

and remove the duplicate line (does not matter which):

http://dl.google.com/linux/chrome/deb/

Then use ctrl-x to exit (y to save). Do an apt-get update and upgrade as you normally would.

  • There were no duplicate entries. The answer from desgua askubuntu.com/questions/120621/… did the trick – Noosrep Jan 27 '15 at 11:14
  • Ah OK, I missed the edit/comment. Are all your problems solved then ? If so, answer your own question with what you did and mark solved :) – NGRhodes Jan 27 '15 at 11:38

  1. Open 'Software & Updates' and go to 'Other software'.
  2. Uncheck the software which is showing error while updating.
  3. Refresh and rerun the update.

Comment those lines, of which this error is producing.

Open Terminal (Ctrl+Alt+T) an run the following commands.

Change to the /etc/apt directory:

cd /etc/apt/

Edit the file sources.list:

sudo nano sources.list

Comment the lines with # symbol which is mentioned in the error log.

Once update the sources.list file, upgrade your software by using the following command line.

sudo apt-get clean    
sudo apt-get update 
sudo apt-get upgrade

Hi best is that whenever you face this problem use the terminal to know what actually stopping it so open terminal and use below command

sudo apt-get clean    
sudo apt-get update 

Update command will show you the URL or Package which is creating a problem, generally this is due to unreliable package like when I ran this I got below error on terminal

W: GPG error: http://dl.google.com/linux/chrome/deb stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 78BD65473CB3BD13
W: The repository 'http://dl.google.com/linux/chrome/deb stable InRelease' is not signed.

So it mean http://dl.google.com/linux/chrome/deb was potential harmful for my computer and that is where you then need to UNCHECK this from update setting panel OR you can update your installation file.

    dl.google.com/linux/chrome/deb was potential harmful: dl.google.com/linux/chrome/deb is the official repository of Google Chrome. I don't see how it was harmful for you. GPG errors generally mean you have added "alien" repositories to the system. Those "alien" repositories may or may not be harmful depending on the source and developer. – Kulfy Sep 13 '20 at 13:55
