Make sure the VM has sufficient RAM allocated to it - I think 652MB is the minimum specified to do a GUI install which is the only one that lets you select packages etc. [by TrevorH]
I'm using ubuntu 9.04. From last few days I'm trying to install a virtualbox,but i can't. I went to this link for virtualbox. https://www.virtualbox.org/wiki/Download_Old_Builds_3_0
Found the virtualbox for my version. After downloading it in xp i restarted my pc and opened ubuntu. While installing by package installer there is a problem.
I have a problem with installing yum in CentOS (version 5.3, 64bits). My CentOS not yet install yum, so i can't install other package that I need. I found out one article that show how to install yum on CentOS (both 32bits and 64bits), but it doesn't work for me.
