According to my analysis the openSUSE 15.1 primary.xml file has a difference
with respect to earlier versions of openSUSE that currently creates trouble in
Uyuni/SUSE Manager.

In the current primary.xml file, some packages appear to be repeated. What I
see is that, for example,
`noarch/arphic-uming-fonts-0.2.20080216.1-lp151.2.1.noarch.rpm` and
`boot/x86_64/arphic-uming-fonts.rpm` are the same file, and both are actually
listed in the primary.xml file. I see this from:

wget

#search for arphic-uming-fonts

Specifically:

<package type="rpm">
  <name>arphic-uming-fonts</name>
  <arch>noarch</arch>
  <version epoch="0" ver="0.2.20080216.1" rel="lp151.2.1"/>
  <checksum type="sha256"
pkgid="YES">7ed08f423996c92cfdf84aaa2f87aef55a26c95ee64f0a92a24d87d87d9be1e5</checksum>
...
  <location
href="noarch/arphic-uming-fonts-0.2.20080216.1-lp151.2.1.noarch.rpm"/>
...
</package>
<package type="rpm">
  <name>arphic-uming-fonts</name>
  <arch>noarch</arch>
  <version epoch="0" ver="0.2.20080216.1" rel="lp151.2.1"/>
  <checksum type="sha256"
pkgid="YES">7ed08f423996c92cfdf84aaa2f87aef55a26c95ee64f0a92a24d87d87d9be1e5</checksum>
<location href="boot/x86_64/arphic-uming-fonts.rpm"/>


(Same package name, arch, epoch, version, release, checksum but different
location)


In the past it was never the case that those `/boot` packages were listed in
the primary.xml file.

A fix is being developed in Uyuni to work around this.
