The news came from Canonical’s Kate Stewart on the Ubuntu Mailing list, who wrote:
There is no longer a traditional CD sized image, DVD or alternate image, but rather a single 800MB Ubuntu image that can be used from USB or DVD.Ubuntu Server, however, remains unaffected by this size change.
Why the increase?
1. Well there is many reasons for this to happen, but the main reason why is to give developers some breathing room. Developers can feel a bit relaxed with they they are creating. This is not that much of a space increase, but you want to keep from bumping put the max file size a lot at one time to avoid the distro from becoming bloated.
Before, developers and Ubuntu maintainers have had to made hard decisions on what to include on the disc image and what can't make its way in. You got to feel bad in this scenario because you don't want to be the one that has to say "no" to a package because you don't have enough space.
2. Secondly, ‘consolidation’ of images and developer effort will play a part.
Prior to Ubuntu 12.10 alternate installer and DVD-sized .iso’s were available to download alongside the main ‘LiveCD’ image. The more images produced, the more time that has to be spent by developers in compiling, checking, bug testing and reviewing each specific build. For Ubuntu 12.10 both of these have been retired.

Installing Ubuntu From Now on Onward
For now on, you will not be able to use a CD. That part is obvious. You are not left in the dark, though. You do have other options, and some actually have benefits over using the CD in the first place. You have these options of installing Ubuntu:
- Via DVD
- Via USB device, such as a flash drive or memory card
- Via the update manager's update distro feature
You won't have an alternative CD, because of reasons specified above in the first few paragraphs. How have you installed Ubuntu recently (or in the past, it doesn't matter)? Let me know in the comments below.
