      Hi all,
      Just hoping to get a hand with setting up ISO booting for Ubunti 18/19 LTS.
      I’ve tried following George1421’s guide and am not having luck copying the vmlinuz or boot files to the ftfpboot directory, as they do not exist on my 18.04 ISO.
      Am I able to get a hand with setting this up? Apologies, I’m relatively new to Linux. I’m not fussed on whether I’m using Ubuntu 18 or 19.

        Forum mentioned: https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images/5

        A small update, I have managed to get the initrd.gz file and have placed that into the tftp directory though I am still unable to find the vmlinuz file.
        In /images/os/ubuntu/18.04/install I have the file “mt86plus”

        I’m going to make the assumption that the vmlinuz kernel file has been replaced with this, and place mt86plus into the tftp directory and test.

        I will report back!

          Nope, no luck 😞
          PXE appears to load the mt86plus file ok (states “ok” on the screen) and very quickly loads the initrd.gz file but once it hits 100%, it exits back to the main PXE boot screen.

            @xardoniak What output do you get from the command ls -al /images/os/ubuntu/18.04/casper? Please post here.

            Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

            Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

              @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.

              Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on 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 MENU

                          I 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

                                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 MENU

                                This 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.
