Ubuntu – Can’t get rid of GPG-error: http://download.opensuse.org

aptkeyserver

I have been googling for hours trying to find a way to get rid of the annoying gpg-error referring to the link below.

W: GPG error: http://download.opensuse.org Release: The following signatures could not be verified because the public key is not available: NO_PUBKEY 9A5EED8CBCA00D90

I have tried:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 9A5EED8CBCA00D90

but to no avail.

Google Translated error message:

The following signatures could not be verified because the public key is not available

If you don't need the source, you can look up and remove/comment the source entries. To find out where they are:

grep -iR opensuse /etc/apt/sources.list*

In all likelihood, they are in the sources.list.d folder, so this command should disable such entries:

sudo sed -i '/opensuse/ s/^/#/' /etc/apt/sources.list.d/*.list

You can ignore files with the .save extension.

APT – How to Fix GPG Error ‘NO_PUBKEY’

By far the simplest way to handle this now is with Y-PPA-Manager (which now integrates the launchpad-getkeys script with a graphical interface).

To install it, first add the webupd8 repository for this program:
```
sudo add-apt-repository ppa:webupd8team/y-ppa-manager
```

Update your software list and install Y-PPA-Manager:

sudo apt-get update
sudo apt-get install y-ppa-manager

Run y-ppa-manager (i.e. type y-ppa-manager then press enter key).
When the main y-ppa-manager window appears, click on "Advanced."
From the list of advanced tasks, select "Try to import all missing GPG keys" and click OK.

You're done! As the warning dialog says when you start the operation, it may take quite a while (about 2 minutes for me) depending on how many PPA's you have and the speed of your connection.
