I installed F7 a few days ago. First thing post install was to use Yum to install Apt, and Synaptic, which I prefer. At the same time as installing these with Yum, a gpg public key was installed (4f2a6fd2-3f9d9d3b), and this in in /etc/apt/gpg, and is shown as a link to /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora. There are a bunch of keys in /etc/pki/rpm-gpg. RPM-GPG-KEY, RPM-GPG-KEY-beta, RPM-GPG-KEY-fedora, RPM-GPG-KEY-fedora-rawhide, RPM-GPG-KEY-fedora-test, and RPM-GPG-KEY-rawhide. When I run apt-get update, it complains about missing keys, says it's fetching them, then fails to import them, but there is no problem installing the updates, and the gpg check runs to completion before installing the updates, which install with no problems. Incidentally I found another public key in /etc/apt/gpg, which is a locked file, and again is a link, and pointing to /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-extras, which of course does not exist for F7, as everything is now in, and excuse the pun, the "everything" repo. The file is (gpg-pubkey-1ac70ce6-41beeef). I started this post before finding the fix, but have continued with it as someone else may have this problem. The fix is to remove the above locked file, as it's unwanted. To verify, I put the file in a new directory, and ran apt-get update. No complaints now. Took the file back out of the directory, and ran apt-get update again, and the complaints about missing keys are back. I suppose I should report this as a bug related to Apt, as this public key ponting to "extras" should not be there. I havn't posted bug reports before, so any pointers how to go about this would be welcome. Nigel.
