[cobbler] Anyone have success installing Ubuntu 15.04?

[Will Dennis]

Hi all,

Have been trying to install Ubuntu 15.04 via Cobbler (both using kickstart and 
preseed) - the install looks normal, completes, but then when the machine 
reboots, it hangs after the BIOS screens where it would normally display the 
GRUB menu... I have tried this process on two different Dell PowerEdge machines 
(an 1850 and a 1950) but the same thing happens every time. I can successfully 
install on either of these machines if I use the regular Ubuntu 15.04 CD to 
install. Anyone seeing this, or have any suggestions on how I might 
troubleshoot? I have booted the Cobbler-installed machines with an Ubuntu 
rescue CD, and did the "reinstall GRUB" option, but they still won't boot 
thereafter...

Thanks,
Will

Hi,
   Maybe it's a pxe config file problem, please, to check this, try to unplug 
the ethernet cable and reboot.

No difference... still does not boot. FWIW, I see that the boot drive is being 
accessed after the BIOS completes, but nothing happens...

Map the iso in and choose the recover mode. See if it can find your OS disk. 
Sounds like it might be a gpt partition issue? How big is the boot disk? Is the 
bios set to legacy of uefi mode? Is secure boot turned off? 

Regarding Ubuntu, we always stick with the LTS versions. Everything else should 
be considered beta. Tried 14.04 LTS? 16.04 is not far off which is the next LTS.

Also you are using the alt/server Ubuntu iso's?

Cobbler does work fine with 14.04 LTS in my shop; I have to deploy 15.04 this 
time because we are a research institution, and the researchers tell me that 
14.04 is too old (packages too old) for the intended research use... And cannot 
wait until 16.04 is out next year. So they want 15.04 deployed.

Thanks,
Will
