When updating packages rpm installs all the new packages first, then cleans up the old packages. So, at no time is the system without at least 1 copy of the package. The most common problem we've run into with yum is getting halfway through a transaction and power or network or something fails such that the second part, cleaning up the older packages, cannot occur. this is where yum-complete-transaction comes in. It will finish up the remaining steps since it has enumerated them. Hope this helps, explain. -sv -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
