I was delighted to find that we now have getvirtualbox for ver. 4.04 in the repositories and that it gives you the option to either install or not in it's dialog box. However even though the install for Virtual Box is straight forward, I found that the installation of the new extpack problimatic.
Oracle says that all you have to do is double click on the downloaded file and then follow the directions. I did not find this to be the case. I had to read through several pages of their documentaion to find the command to install it from the command line. Shouldn't this be easier?
I think new users will be baffled so here is the command I found:
VBoxManage extpack install <name of extpack without brackets>
Oracle's doc's say that the install of the extpack is not a problem for experience linux installers
What about those of us who don't install everyday or are fairly new?
It took entirely too long for me to get this done, and I've worked with several different distro's for several years.
