Downloading ubuntu and creating a bootable dvd
These instructions assume one is running on an existing rhel6-64 machine.
- At https://ubuntu.com, select "Ubuntu Desktop" LTS (Long-term support) which is currently v18.04.2
- Download. The file should be ubuntu-18.04.2-desktop-amd64.iso and is about 1.9 GB in size
- Insert a fresh DVD (4.7 GB) into the drive
- $ cdrecord -v -dev='/dev/scd0' ubuntu-18.04.2-desktop-amd64.iso
If you are uncertain as to the proper device name, you may use the command "cdrecord --devices" to find out.
