E: Some index files failed to download. They have been ignored, or old ones used instead.

I tried sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3EF2666A18CEC0F6

but it is not working

I also tried

sudo rm /var/lib/apt/lists/* -vf

after that I tried using y-ppa-manager

but still getting error

Which repo have you added? Did you import the pgp key?

[rajan9]

No I have not Imported any pgp key.

I am having this error from long time. recently I upgraded to libreoffice 4.4.0 and now I am not able to update or updade my system (ubuntu 12.04). It shows above mentioned error and update fails.

Thank you in advance

hmm, why is the PPA mentioned? We only care for the OBS packages here.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3EF2666A18CEC0F6

Does not know about opensuse keys. Try pulling the key from opensuse instead:

wget -nv http://download.opensuse.org/repositories/isv:/ownCloud:/community:/8.0/xUbuntu_12.04/Release.key -O Release.key
apt-key add - < Release.key

@rajan9 Would that help? Adapt the url, if you used a different one.

#5067 is probably related. I of course did as the instructions said
