DNF error: Error in POSTIN scriptlet in rpm package srvadmin-cm

Solution In Progress - Updated -

Environment

  • Red Hat Enterprise Linux (RHEL) 8

Issue

  • Anaconda install fails with the following when doing minimal install, but including 3rd party srvadmin-base RPM.

    <snip>
Installing srvadmin-cm.x86_64 (130/367)
=====================================================================
Error

The following error occurred while installing.  This is a fatal error and
installation will be aborted.

DNF error: Error in POSTIN scriptlet in rpm package srvadmin-cm

Resolution

  • The 3rd party RPM needs to add RPM dependency on coreutils RPM and/or ln binary.

Work Around

  • Install RHEL without the 3rd party srvadmin RPMS. Then after the OS is installed, which will include coreutils RPM, install the 3rd party srvadmin RPMs.

Root Cause

  • None of the Dell (3rd party) RPMs have a require on ln or coreutils

    # rpm -qa | grep srvadm
srvadmin-deng-9.5.0-4063.16816.el8
srvadmin-isvc-9.5.0-4063.16816.el8
srvadmin-base-9.5.0-4063.16816.el8.
srvadmin-cm-9.5.0-20.09.00
srvadmin-omilcore-9.5.0-4063.16816.el8
srvadmin-smcommon-9.5.0-4063.16816.el8
srvadmin-hapi-9.5.0-4063.16816.el8
srvadmin-ominst-9.5.0-4063.16816.el8
srvadmin-xmlsup-9.5.0-4063.16816.el8
srvadmin-omacs-9.5.0-4063.16816.el8

# rpm -q --requires $(rpm -qa | grep srvadm) | egrep -c 'coreutils|ln'

Diagnostic Steps

  • From one of the anaconda shell windows, like the tmux shell window (control-b,2), view the dnf history via chroot of the installing image.

    [anaconda root@localhost ~]# chroot /mnt/sysimage/
[anaconda root@localhost ~]# dnf history info 1 | egrep -B1 'Scriptlet|exit status'
    Install @platform-kvm                                                    
Scriptlet output:
--
   7 /var/tmp/rpm-tmp.GSYac7: line 2: ln: command not found
   8 warning: %post(srvadmin-cm-9.5.0-20.09.00.x86_64) scriptlet failed, exit status 127

  • Looking at the rpm scripts, can see it is doing ln command

    [anaconda root@localhost ~]# rpm -q --scripts srvadmin-cm | grep -A2 ^postinstall
postinstall scriptlet (using /bin/sh):
   # create sym link to use 64 bit invcol
   ln -sf /opt/dell/srvadmin/sbin/lx64/invcol /opt/dell/srvadmin/sbin/invcol

  • ln is provided by coretuils

    # rpm -q --whatprovides /bin/ln
coreutils-8.30-8.el8.x86_64

# rpm -q --whatprovides /usr/bin/ln
coreutils-8.30-8.el8.x86_64
