Installation fails, booted live CD from PXE

[Rodolfo Alexis Lam Figueroa]

Version: Ubuntu 15.10 Release 15.10

Ubiquity Version: 2.21.37

Lubuntu Live iso booted from network in PXE mode using Serva application running on Windos 10 Pro.

Desktop loaded successfully and system works as normal.

Install started from built-in GUI installer. Threw an error about unable to verify CD-ROM signatures or something like that. Possible cause might be no CDROM is used at all. System is running from RAM.

Forgot to mention, the installer worked correctly all the way to the start of the installation itself (Choose where to install, region, PC/user name and password).
