Leapp upgrade RHEL8.10 to RHEL9 failed with error, PID: 109803 leapp.workflow.Download.dnf_package_download: file /boot/efi/EFI/redhat/shim.efi from install of shim-x64-15.8-4.el9_3.x86_64 conflicts with file from package shim-ia32-15.8-4.el8_9.x86_64

Solution Verified - Updated

Environment

  • Red Hat Linux 8 for 8x6_64
  • Leapp upgrade to RHEL9

Issue

  • Leapp upgrade RHEL8.10 to RHEL9 failed with error,
PID: 109803 leapp.workflow.Download.dnf_package_download:   file /boot/efi/EFI/redhat/shim.efi from install of shim-x64-15.8-4.el9_3.x86_64 conflicts with file from package shim-ia32-15.8-4.el8_9.x86_64

Resolution

  • Update the RHEL8* packages to the latest RHEL8.10.z
    leapp-upgrade-el8toel9 must be updated to the latest release "leapp-upgrade-el8toel9-0.21.0-2.el8_10"

WORKAROUND if RHEL8 packages cannot be updated

  • Add shim-ia32 package to the file /etc/leapp/transaction/to_remove
# cat /etc/leapp/transaction/to_remove
### List of packages (each on new line) to be removed from the upgrade transaction
# Removing initial-setup package to avoid it asking for EULA acceptance during upgrade - OAMG-1531
shim-ia32
  • Alternatively, remove the "shim-i32" package before running leapp:
# yum remove shim-ia32

Root Cause

  • RHEL9 does not support ia32 hence shim-ia32 package is no longer included.
    But shim-ia32 package in RHEL8 provides /boot/efi/EFI/redhat/shim.efi which is also provided by the RHEL9 shim-x64, so a conflict occurs.
  • Latest released "leapp-upgrade-el8toel9-0.21.0-2.el8_10" addressed the shim-ia32 package conflict issue

Diagnostic Steps

  • Check the installed shim package in RHEL8;
# rpm -qa|grep shim*
shim-ia32-15.8-4.el8_9.x86_64      
shim-x64-15.8-4.el8_9.x86_64 

# rpm -ql shim-ia32

/boot/efi/EFI/redhat/shim.efi   <==============
/boot/efi/EFI/redhat/shimia32-redhat.efi
/boot/efi/EFI/redhat/shimia32.efi
  • Check the installed shim package on existing RHEL9
# rpm -qa|grep shim
shim-x64-15.8-4.el9_3.x86_64

[root@sat616 ~]# rpm -ql shim-x64
