Title: Detected custom leapp actors or files.
Summary: We have detected installed custom actors or files on the system. These can be provided e.g. by third party vendors, Red Hat consultants, or can be created by users to customize the upgrade (e.g. to migrate custom applications). This is allowed and appreciated. However Red Hat is not responsible for any issues caused by these custom leapp actors. Note that upgrade tooling is under agile development which could require more frequent update of custom actors.
The list of custom leapp actors and files:
- /usr/share/leapp-repository/repositories/system_upgrade/common/files/rpm-gpg/8/RPM-GPG-KEY-AlmaLinux-8

Remediation: [hint] In case of any issues connected to custom or third party actors, contact vendor of such actors. Also we suggest to ensure the installed custom leapp actors are up to date, compatible with the installed packages.

Risk Factor: high
Title: Detected customized configuration for dynamic linker.
Summary: Custom configurations to the dynamic linker could potentially impact the upgrade in a negative way. The custom configuration includes modifications to /etc/ld.so.conf, custom or modified drop in config files in the /etc/ld.so.conf.d directory and additional entries in the LD_LIBRARY_PATH or LD_PRELOAD variables. These modifications configure the dynamic linker to use different libraries that might not be provided by Red Hat products or might not be present during the whole upgrade process. The following custom configurations were detected by leapp:

  • The following drop in config files were marked as custom:
    • /etc/ld.so.conf.d/vmware-tools-libraries.conf
      Remediation: [hint] Remove or revert the custom dynamic linker configurations and apply the changes using the ldconfig command. In case of possible active software collections we suggest disabling them persistently.

Risk Factor: high
Title: GRUB2 core will be automatically updated during the upgrade
Summary: On legacy (BIOS) systems, GRUB2 core (located in the gap between the MBR and the first partition) cannot be updated during the rpm transaction and Leapp has to initiate the update running “grub2-install” after the transaction. No action is needed before the upgrade. After the upgrade, it is recommended to check the GRUB configuration.

Risk Factor: high
Title: BIND configuration issues found
Summary: Default value of listen-on-v6 have changed, but it is not present in configuration. named service will now listen on INET6 sockets also.

Risk Factor: high
Title: Difference in Python versions and support in RHEL 8
Summary: In RHEL 8, there is no ‘python’ command. Python 3 (backward incompatible) is the primary Python version and Python 2 is available with limited support and limited set of packages. If you no longer require Python 2 packages following the upgrade, please remove them.

Remediation: [hint] Please run “alternatives --set python /usr/bin/python3” after upgrade

Risk Factor: high
