You need to figure out what about the pre script is failing ... here is
what is contained in the pre script:
rpm -q --scripts openssh-server
and
rpm -q --scripts xorg-x11-xfs
Then look at the preinstall sections (which looks like what is failing).
It seems that the code in question is (for openssh):
------------------------------------------------------
preinstall scriptlet (using /bin/sh):
/usr/sbin/useradd -c "Privilege-separated SSH" -u 74 \
-s /sbin/nologin -r -d /var/empty/sshd sshd 2> /dev/null || :
------------------------------------------------------
and for xorg-x11-xfs:
------------------------------------------------------
preinstall scriptlet (using /bin/sh):
{
# Conditionalized to work on RHL 7.1 and 7.2 which do not
have /sbin/nologin
LOGINSHELL=$([ -e /sbin/nologin ] && echo /sbin/nologin ||
echo /bin/false)
/usr/sbin/useradd -c "X Font Server" -r -s $LOGINSHELL -u 43 -
d /etc/X11/fs xfs || :
} &> /dev/null || : # Silence output, and ignore errors (Bug #91822)
------------------------------------------------------
There are a couple things in common here ..
1. They both use useradd ... make sure root can do that where you are
getting the error.
2. Both commands direct output to /dev/null ... make sure that exists
in the place the installs are happening.
IF this was a chroot and not xen, I would recommend that you ensure that
selinux was off in the chroot ... maybe the same applies inside xen
clients (I am not sure about that).
