I've just installed FC3 on my desktop machine and have attempted to update with yum. Some packages would install/update OK while others would complain that there was no public GPG key available. I've added GPG keys per instructions at http://www.fedorafaq.org and even have commented out the gpgcheck lines in my yum.conf downloaded from http://www.fedorafaq as well. That was issue #1. Since then I have installed yumextender as well, per a post I saw on this list. Looks and works good, but of course was suffering the same errors as when using yum from console. Something has since gone awry as I cannot update yum and yumextender will no longer start since I changes some repos. I get the following: [root@localhost etc]# yum check-update not using ftp, http[s], or file for repos, skipping - None Setting up Repo: livna-stable repomd.xml 100% |=========================| 951 B 00:00 Setting up Repo: fedora-unstable repomd.xml 100% |=========================| 903 B 00:00 Setting up Repo: fedora-stable repomd.xml 100% |=========================| 903 B 00:00 Setting up Repo: livna-unstable repomd.xml 100% |=========================| 951 B 00:00 Setting up Repo: updates-released repomd.xml 100% |=========================| 951 B 00:00 Setting up Repo: livna-testing repomd.xml 100% |=========================| 951 B 00:00 Setting up Repo: base Cannot find a valid baseurl for repo: base My yum.conf file mentions that base repos are located at /etc/yum.conf.d/ but this directory isn't present currently on my system. What I'm trying to do is to select repositories that will hopefully not conflict while at the same time make use of bleeding-edge packages where possible. Any help is greatly appreciated.
