The command

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EB9B1D8886F44E2A

should help.

Or you can try re-adding the PPA with the command
sudo add-apt-repository ppa:openjdk-r/ppa

As u suggested, if i go with first command(sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EB9B1D8886F44E2A),
i have got the following Error:

The responses are unexpected.

What do you get when you try accessing the web page
http://keyserver.ubuntu.com/pks/lookup?search=0xEB9B1D8886F44E2A

Maybe there was some kind of temporary problem; if you try again, do you still get the same error messages?

Maybe the manual procedure as shown in https://askubuntu.com/a/457549 works for you.

1. You have separate question for that - https://answers.launchpad.net/ubuntu-fr-secours-sourceslist/+question/642560 and for keeping the "one question - one topic" principle I recommend that you mark this question as solved and use the other one for the "user or group does not exist" problem.

2. You have created these two questions in a wrong area. "sources-list" ubuntu-fr-secours-sourceslist is a project for creating sources.list files as part of the French Ubuntu users group - apparently dead (Ubuntu 10.04 is listed as the newest release).
I suggest that you move the question documents into the general "Ubuntu" area by using the "edit" button in the header of the question document.

Can you help with this problem?
