I have some problems updating my Ubuntu
Requires installation of untrusted packages
The action would require the installation of packages from not authenticated sources.
cinnamon gir1.2-muffin-3.0 libgnome-keyring-common libgnome-keyring0 libmuffin0 muffin-common
The downloads are from the Main server, the Source code under Ubuntu Software tab is marked
Is there something I have missed?
The output of sudo apt-get update is:
W: GPG error: http://ppa.launchpad.net oneiric Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6A9653F936FD5529
