On CentOS 5.9 i686 running WHM 11.38, I was attempting to upgrade mysql from 5.0 to 5.5 using shell instead of WHM because I was told it was safer that way as it would keep the old mysql lib intact and my sites would have no downtime. HA. The shell upgrade failed. So I attempted to upgrade using WHM mysql upgrade and that failed.
Trying to upgrade i receive a message "authenticating the upgrade failed,there may be a problem with the network or the server".
Can we upgrade from 11.04 full iso CD, in this case witch version(desktop,server or alternate)?
