Hi List,

i am trying to autoinstall SLES15 systems but my autoinstall distribution seems to have problems. After booting (PXE) i get a gray tui box on blue background saying " Please make sure your installation medium is available". The URL in "install" Kernel Parameter of the distro was generated automatically, i did not change it. When i try to accessit with browser i get an error message: Internal Server Error

The server experienced a problem which prevented your request from being filled out. It may not be possible to execute this action at this time.

Please help us correct this problem by contacting us with details of how you received this message.

URLs of other Distros can be accessed w/o errors. I deleted and re-created the Distro, rebuilt the (staged/contentlifecycle) Repo, both without luck.

Any hint is welcome!

Thanks! Heiner

Hi List, i found the Problem within my autoinstall Distro. Context: I found the hint / "best practise", that i should create an autoinstall distro for each profile. Now i my distro config used in a faulty profile i changed the kernel Parameters (default, they were automatically filled in at creation) to a tree path that works in another distro. With this path my installation worked. Next, i completely selected that working "Autoinstall Tree" to be used by my faulty profile, that worked, too. Why should i use a separate autoinstall distro / tree for each profile (if they are all the same os version like "sles 15 sp2")? BR Heiner
