Hoje realizaremos o processo de atualização do Oracle Linux 8 para o Oracle Linux 9 usando o utilitário Leapp. Lembre-se sempre de testar todos os serviços, pacotes e aplicações antes de migrar seus servidores para produção.
O utilitário Leapp é um utilitário para atualizar sistemas operacionais e aplicativos.
As operações da Leapp consistem em duas fases: uma fase de pré-atualização que executa verificações do sistema para determinar se o software pode ser atualizado. A segunda fase é a atualização propriamente dita, cujo processo é baseado em arquivos de configuração que mapeiam os pacotes entre as versões anteriores e atuais do software.
1 – Confirmando que nossa versão do Oracle Linux é 8.

Risk Factor: high (inhibitor)
Title: The OS Management Service (OSMS) agent is running on this instance.
Summary: The OSMS service is active on this instance.
The OS Management Service does not currently support Oracle Linux 9 AppStreams, also known as modules or module streams.
Upgrade cannot proceed with the OSMS agent active. Please refer to https://docs.oracle.com/en-us/iaas/os-management/osms/osms-getstarted.htm for more information about OSMS and Oracle Linux 8.
Remediation: [hint] The OSMS agent is included in OCI Oracle Linux platform images and installed by default. If the instance is not actively managed by OSMS, the OSMS agent can be disabled from the OCI console and the upgrade can proceed. Please refer to https://docs.oracle.com/en/operating-systems/oracle-linux/9/leapp/ for information about disabling the OSMS agent.

----------------------------------------
Risk Factor: high (inhibitor)
Title: Firewalld Configuration AllowZoneDrifting Is Unsupported
Summary: Firewalld has enabled configuration option "AllowZoneDrifiting" which has been removed in OL9. New behavior is as if "AllowZoneDrifiting" was set to "no".
Remediation: [hint] Set AllowZoneDrifting=no in /etc/firewalld/firewalld.conf
[command] sed -i "s/^AllowZoneDrifting=.*/AllowZoneDrifting=no/" /etc/firewalld/firewalld.conf
Key: 5b1cf050e1a877b0358b6e8c612277c591d40c13
----------------------------------------
Risk Factor: high
Title: Packages not signed by Oracle found on the system
Summary: The following packages have not been signed by Oracle and may be removed during the upgrade process in case Oracle-signed packages to be removed during the upgrade depend on them:
- gpg-pubkey
Key: f5a5d58476a97bf0a8904d00df5d1321189849ad

Title: Default Boot Kernel
Summary: Setting default boot kernel in OL9 to RHCK
Key: 536a8dee211d9f0998aa21f8e5bcd9f3beaf022d
----------------------------------------
Risk Factor: low
Title: SElinux will be set to permissive mode
Summary: SElinux will be set to permissive mode. Current mode: enforcing. This action is required by the upgrade process to make sure the upgraded system can boot without beinig blocked by SElinux rules.
Remediation: [hint] Make sure there are no SElinux related warnings after the upgrade and enable SElinux manually afterwards. Notice: You can ignore the "/root/tmp_leapp_py3" SElinux warnings.
