Ubuntu "engineers" are probably dumber than that Enterprise Linux OS. I got a laptop from a friend who asked me to install the latest Ubuntu on it. My usual technique of make a live bootable usb faild.
So, I googled and found this evidence that Ubuntu engineers are retarded.
You need Ubuntu to install Ubuntu.
This reminds me a bit that Redmond company. What if I have another OS ? NOT Mac or Windows ? For example, Debian? can't you just write how to obtain that package ???
