What did you do, if the content file contained multiple products? Took the first one, or the last one? Do the same here.
IIRC the /content file can only contain one product.
Or take the name from media.1/products. AFAIK this file was invented to be the catalog of repos located on the medium. If the file is no longer available we should think about adding it again.
That file is no longer available, the current LeanOS ISO contains only the "media.1/build" file with "SLE-15-Leanos-DVD-x86_64-Build87.1" content.
The /media.1/products file is still read by libzypp:
[zypp] Exception.cc(log):137 MediaHandler.cc(getFile):1245 THROW: File './media.1/products' not found on medium 'cd:///?devices=/dev/disk/by-id/scsi-0 QEMU_QEMU_CD-ROM_cd0'
So adding that file should hopefully fix the problem.
Stefan, who is responsible for the new product builder?
