ISO Boot Ubuntu 18/19 LTS
-
@xardoniak Did you read the text in red in my article, but you need to download the netboot versions of these kernels and inits. These are needed to boot ubuntu over the network. But TBH I have not tested ubuntu 18 or 19 with FOG.

@george1421 Hi George!
Yeah, I did! I have just removed and replaced my initrd.gz with installer/amd64/initrd.gz from the netboot.tar.gz file here incase I did something wrong.Still the same - loads the mt86plus and closes back to the main pxe boot screen once the initrd.gz file has downloaded
-
@xardoniak While I haven’t looked into the new ubuntu version the kernel still should be vmlinuz I would think that mt86plus is wrong.
-
@george1421 I’ll copy the vmlinuz file from images/os/ubuntu/18.04/casper into tftpboot, update the parameters and report back!
Thanks for your time!
-
@xardoniak I just downloaded 18.0.4 lts and vmlinuz is in the /casper directory. But again you need to kernel and inits from the netboot download, not what is on the dvd. This is because the netboot kernel and inits have nfs enabled to remote mount the image share.
For 18.04 the netboot path is here: http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/
-
OK, so I have
- Downloaded vmlinuz file from here and placed it in /tftpboot/os/ubuntu/18.04/
- Downloaded the netboot.tar.gz file from here, extracted and copied /ubuntu-installer/amd64/initrd.gz to /tftpboot/os/ubuntu/18.04/
- Updated Peramaters
kernel tftp://$10.0.70.10/os/ubuntu/18.04/vmlinuz initrd tftp://$10.0.70.10/os/ubuntu/18.04/initrd.gz imgargs vmlinuz initrd=initrd.gz root=/dev/nfs netboot=nfs nfsroot=$10.0.70.10:/images/os/ubuntu/18.04/ locale=en_US.UTF-8 ip=dhcp rw boot || goto MENUI am now getting this error: https://pasteboard.co/IxKBqW4.png
Also see to the right, dir outputs for the tftboot and images directory.I’m sure I’ve missed something, somewhere…

@xardoniak Ah, common mistake. If you leave the ${fog-ip} or what ever it was in the tutorial exactly as it was in the tutorial the fog server will dynamically replace that value with its current IP address. The other option is to just remove the dollar sign, because that is part of the variable name.
Edit: I just went and grabbed that section of the tutorial.
${fog-ip}is the complete variable name, you can just paste it in directly (but fix the path for the different version of ubuntu)kernel tftp://${fog-ip}/os/ubuntu/16.04/vmlinuz initrd tftp://${fog-ip}/os/ubuntu/16.04/initrd.gz -
@george1421 I knew I was doing something stupid… I’ve got the Ubuntu set up screen! Thanks so much!

@xardoniak
I was using Ubuntu 18 Server install, but I was able to get it working like this.I created a /images/os/ubuntu folder and copied the ubuntu ISO file contents in there.
I created a folder /tftpboot/os/ubuntu
There I put the initrd and vmlinuz files from the casper folder in the ubuntu iso.Here are the parameters I used in FOG.
kernel tftp://192.168.160.12/os/ubuntu/vmlinuz
initrd tftp://192.168.160.12/os/ubuntu/initrd
imgargs vmlinuz initrd=initrd boot=casper root=/dev/nfs netboot=nfs nfsroot=192.168.160.12:/images/os/ubuntu/ ip=dhcp rw
boot || goto MENUThis allowed me to start the installer from that usb, but I haven’t got a working live OS running yet, though I hope to have that soon.
