FWIW, similar to JC, but a little diferent methodology:

I usually go here to get rpm's for the 1.75 when yum is misbehaving

http://arm.koji.fedoraproject.org/koji/builds

Also:

One of the first things I then do is download the current versions of the
following little guys onto a USB then do a yum localinstall from there for
1.75 gadget testing:

bind-libs
bind-utils
gparted
ntp
ntpdate
putty
traceroute
usbutils
yum-plugin-downloadonly
yum-utils


Cheers,

KG
