With 2.4.0, I have been getting a lot of these errors lately: Error: Requiring package libxml2-python-2.6.21-4.el3 not in transaction set nor in rpmdb Error: Requiring package python2.4-devel-2 not in transaction set nor in rpmdb libxml2-python-2.6.21-4.el3 -> libxml2-devel-2.6.21-3.el3.pyv python2.4-devel-2 -> python2.4-devel-2.4-1pydotorg There really is another error buried underneath: either the packages conflict or an Obsoletes is not being processed. In my case, my python24-devel package does not properly Obsolete python2.4-devel. However, because somehow Yum is cutting off the %{release}, it probably cannot determine the actual problems because the cut off package is *not* in the transaction set. Anyone else seeing this behavior? I'll try to peel away the layers, but the pattern that I am seeing is that the %{release} is cut off in the wrong way. -- -jeff
