I want to report that I was able to successfully install the daily builds from both Ubuntu and Xubuntu in virtual machines using Boxes on Gnome.
I am using older architecture, an HP Pavilion G6 with BIOS, not UEFI. i3 processor with 8GB RAM.
No issues encountered during the installs.
I do, however, have one comment but am not sure to whom this should be addressed:
On the screen about Help it mentions Ask Ubuntu first and then Discourse.
Perhaps Canonical, the developers might want to consider making Ubuntu Discourse more prominent since it is now merged with Ubuntu Forums?
The desktop download of Feb 14 would not install. In the live session, clicking on the install icon results in a core dump. This happened in Virtualbox and my thinkpad laptop.
