Re: Yum error - "Couldn't resolve host"

Thank you, marko! I wasn't aware of the default ipv6 setting in Fedora. This is most likely the entire issue. And, no, I don't have an HTTP proxy.

The first thing I always have to do with Firefox is toggle ipv6 off, so your comment makes perfect sense. I'll check through the forums for a proper how-to. I know that different distros prefer different ways of blacklisting/commenting out, etc.

I also found (finally) the Software Management Guide (http://docs.fedoraproject.org/en-US/...agement_Guide/) at last. In the morning I'll check through the forums for disabling ipv6 as default and give that a whirl.

So many words to get such a simple answer...that's me in a nutshell :-)

It's also a really good idea to set your network.dns.disableIPv6 setting in Firefox to true

You do that by putting about:config into firefox as the url and toggle the network.dns.disableIPv6 to true

Re: Yum error - "Couldn't resolve host"

It's been an ipv6 issue all along. Once /etc/modprobe.d/blacklist.conf included the lines:
blacklist ipv6
install ipv6 /bin true

and /etc/sysconfig/network included the line:
NETWORKING_IPV6=no

and /etc/sysctl.conf included the line:
net.ipv6.conf.all.disable_ipv6=1

and then a reboot, running lsmod | grep ipv6 as root returned nothing.

Then going to PackageKit, everything installed just fine

After having read about disabling ipv6 through the blacklist.conf file, I remembered that I had to go through the same thing when I test-drove F10 for a few days after its release. I'd merely forgotten that Fedora required more than simply toggling Firefox to disabling ipv6, which is all the Debian distros require.

Ah, such a fool...Someone should really post a specific sticky about disabling ipv6 upon reboot after installation, since adoption is still glacial across most ISPs. It would save a lot of energy for *real* issues. Oh, well.
