Hi, If I try to follow the upgrade procedure you recommended, I get the message: package yum-conf-41-4.SL is already installed Does this mean my yum is set up to update to sl41? I did yum update, it updated only 7 packages. However, I should note here that a couple of days ago I had updated my system from the SL repos using up2date, which had installed 143 packages... does this mean that I have a complete system from SL repos?
