Hi List, for autoinstalling SLES15-SP4 i tried to use the Data from tftpboot-installation package as stated in Uyuni Client Config Documentation "Distribution Based on a RPM Package." (https://www.uyuni-project.org/uyuni-docs/en/uyuni/client-configuration/autoi...) i queried RPM "tftpboot-installation-SLE-15-SP4-x86_64-16.57.20-150400.1.18.noarch.rpm" on my uyuni Server and found out it installs into "/usr/share/tftpboot-installation" My autoinstall distro files are stored in "/var/autoinstall" where i have plenty of space, so i symlinked: ln -s /var/autoinstall/tftpboot-installation /usr/share/tftpboot-installation After "zypper install"ing said RPM i found this content in "/var/autoinstall/tftpboot-installation/SLE-15-SP4-x86_64/": EFI README boot net In uyuni gui i created my autoinstall distro using tree path "/var/autoinstall/tftpboot-installation/SLE-15-SP4-x86_64" and created matching profile and activation key. I found no special instructions in documentation when using tftpboot-installation instead of full ISO, so i sticked to the defaults. Cobbler shows my new autoinstall distro/profile. When trying to install a System it is able to load linuxrc but says "installation medium unavailable". Uyuni Tomcat logs this: 2022-08-24 15:39:44,266 [ajp-nio-0:0:0:0:0:0:0:1-8009-exec-1] ERROR com.redhat.rhn.frontend.action.common.DownloadFile - //var/autoinstall/tftpboot-installation/SLE-15-SP4-x86_64/content Not Found .. 404! 2022-08-24 15:39:44,272 [ajp-nio-0:0:0:0:0:0:0:1-8009-exec-8] ERROR com.redhat.rhn.frontend.action.common.DownloadFile - //var/autoinstall/tftpboot-installation/SLE-15-SP4-x86_64/repodata/repomd.xml Not Found .. 404! 2022-08-24 15:39:44,278 [ajp-nio-0:0:0:0:0:0:0:1-8009-exec-3] ERROR com.redhat.rhn.frontend.action.common.DownloadFile - //var/autoinstall/tftpboot-installation/SLE-15-SP4-x86_64/media.1/products Not Found .. 404! It seems like i must set a special path to further Data (media/repos) that isn't included in tftpboot-installation but i don't know what to configure where. For older SLES SPs i downloaded the full 12GB install iso (like "SLE-15-SP3-Full-x86_64-GM-Media1"), unpacked it and put all files into uyuni "tree path" directory of its autoinstall distro. It would be great if i wouldn't need that extra space for SP4 as all RPMs are already stored within my synced Upstream/Product and CLM Repos. Any hint is much appreciated! Thanks, Heiner
