Thanks for your response. If foo-0.6.0 is installed this command takes no
action. I think it would work if you first did install, then update like this:
sudo yum install 'foo <= 0.7.9'
sudo yum update 'foo <= 0.7.9'
But if only 0.6.0 was available in your repos this would succeed even though
it shouldn't have :(
If you can guarantee your repo will have a package that will satisfy
the minimum
dependency this is a good, simple, solution.

I came up with this:
import yum
yb = yum.YumBase()
a = yb.returnPackagesByDep('foo >= 0.7.8')
b = yb.returnPackagesByDep('foo <= 0.7.9')
pkgs = list(set(a) & set(b))
print(yb.bestPackagesFromList(pkgs))
Other than the annoyance that I have to run it as root (I get
IOError: [Errno 13] Permission denied:
'/var/cache/yum/x86_64/6Server/csi/repomd.xml.old.tmp'
when I don't) it works ok.
Thanks!
Jay
