I am attempting to install jessie on a Dell Poweredge R815. It has been running wheezy reliably for years. And running squeeze reliably for years before that. But no matter what I try it won't install or boot.
I have tried two ways. 1. I attempt a fresh install from a USB dongle. It gets all the way to installing grub and then fails. 2. I do a fresh install of wheezy from a USB dongle. It boots wheezy just fine. I do nothing but nano /etc/apt/sources.list (change all instances of wheezy to jessie, save, and exit) apt-get update apt-get dist-upgrade (It upgrades without error. I answer the default to all questions.) /sbin/reboot Then it fails to reboot and goes into the initramfs. I have a picture of the screen if anybody wishes. I can reliably install and run wheezy over and over. I have not been able to install or boot jessie despite numerous attempts. Any suggestions? Jeff (http://engineering.purdue.edu/~qobi)
