Any install that I'm trying through the Software Center is telling me:
Requires installation of untrusted packages: The action would require the installation of packages from not authenticated sources.
I did an
apt-get update from the command line, then removed the software sources that the keys were bad from (PPAs I added myself), and unchecked them in the software sources for software center, but to no avail. I can't install anything from software center anymore - only> from the command line with apt-get.
Is uninstalling/installing the only option? I don't want to break other PPAs that I have.
Here's a paste from apt-get update:
Reading package lists... Done 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 B725097B3ACC3965 W: GPG error: http://us.archive.ubuntu.com oneiric Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <email@example.com>
I've tried apt-key update, and there was no effect (two keys unchanged).
The output of
apt-get update and
apt-get upgrade, and the contents of
/etc/apt/sources.list, can be found in this pastebin post.
