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?

Legacy

Yes

Yes, the server one


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
