A new installer for Ubuntu servers has been released

During the 17.04 development cycle, the Ubuntu Foundations team has been working on a new experimental installer for servers. We are now ready to get feedback from a wider audience.

A 17.04 technical preview image for Ubuntu Server using the new subiquity installer is available here:

http://cdimage.ubuntu.com/ubuntu-server/zesty/tech-preview/

We'd love to get your feedback on it!

It can be used as an ISO image when booting a virtual machine, or burnt to CD/written to a USB key to test on actual hardware, just as you would the official server ISO image;
see https://help.ubuntu.com/community/BurningIsoHowto for more information.

While the installer experience is all new and covers only a subset of the use cases supported by the standard server image, once installed you should find the same Ubuntu Server environment that you know and love. If you notice any differences, please send us bug reports at https://bugs.launchpad.net/ubuntu/+source/subiquity/+filebug

Finally, there are some known issues we're working on already:

- The proposed updates are enabled on the installed system, which is strongly discouraged for a production system. This can be fixed by removing the file /etc/apt/sources.list.d/proposed.list.
- There are no login prompts on virtual terminals other than VT1 (which means you can't hit Ctrl-alt-F2 to switch to a shell).

I'll take this moment to thank Michael Hudson-Doyle, who has done a huge amount of work on getting this ready, as well as Ryan Harper and Adam Stokes who drove early development
of subiquity.
