From: ShaoHe Feng <shaohef(a)linux.vnet.ibm.com&gt; I have not test this patch on ubuntu. I just test the yum patch. We should make sure: 1. apt-get packages list can be updated after apt-get update a package. 2. there should not be a apt-get lock conflict when get apt-get packages list and update apt-get packages.
