Rocky does not support upgrading from CentOS 7. Install a new Rocky system and migrate your data from the CentOS 7 machine to the new Rocky one. ---

After upgrading from centos 7 to centos 8, Should I upgrade to rocky8? ---

The situation is the same and you will likely face the same exact error. It won’t be a supported system here or with the CentOS community. You are recommended to install a new system and migrate your data. Based on the issue you have, you may want to remove javapackages-tools before performing the upgrade and install it after finishing. Other than that, if you insist on performing an upgrade (I will assume you are using ELevate), you will need to work with the maintainers of the software you’re using to work through any other issues you may face. ---

> [@leeminbeom](#): > > After upgrading from centos 7 to centos 8, > Should I upgrade to rocky8? Each RHEL major version is a distinct distro. Same is true for CentOS and Rocky. Yes, one can and often does call replacing one distro with newer major version an _upgrade_. Some might call it _migration_. What CentOS and Rocky do support is fresh install followed by deploying _appropriate_ config and transfer of user data. If one has to work with only one machine and cannot retain old “data partitions”, then one has to restore user data from backups. IMHO, what the Red Hat’s leapp (and derivatives, like ELevate) try to do is _automated in-place conversion_ from one distro to another. Some systems tend to have configurations/customizations set “by hand” – something no automation is prepared to parse and thus will fail. One really has to talk to the maintainers of those conversion tools in order to get them handle more cases. Personally, I rather install fresh. (I have a procedure for that, so it is “routine” by now.) * * * CentOS [Linux] 8 is dead. It has been dead over three years now. When CentOS 8 was still alive, it was possible to _sidegrade_ CentOS 8.4 → Rocky 8.4 (and later CentOS 8.5 → Rocky 8.5). These were “safe and supported conversions” because those distros were practically identical. There exists CentOS Stream 8, but that distro differs from the EL8 distros. It will also die before CentOS 7. ---

Hi there, I had the same problem as described. My solution is as following: 1.) Deinstall the following components yum erase -y _java_ yum erase -y _brotli_ yum erase -y openssl11-libs 2.) Do an Elevate-Upgrade to migrate directly from CentOS 7 to Rocky 8. It is mostly those commands: yum clean all yum makecache fast yum update -y yum install -y [http://repo.almalinux.org/elevate/elevate-release-latest-el$](http://repo.almalinux.org/elevate/elevate-release-latest-el$)(rpm --eval %rhel).noarch.rpm yum install -y leapp-upgrade leapp-data-rocky leapp preupgrade leapp answer --section remove\_pam\_pkcs11\_module\_check.confirm=True export LEAPP\_OVL\_SIZE=3584 leapp upgrade 3.) Postmigrationtasks are documented here > **[Chapter 8. Performing post-upgrade tasks Red Hat Enterprise Linux 8...](https://access.redhat.com/documentation/de-de/red_hat_enterprise_linux/8/html/upgrading_from_rhel_7_to_rhel_8/performing-post-upgrade-tasks-rhel-7-to-rhel-8_upgrading-from-rhel-7-to-rhel-8)** > > Access Red Hat’s knowledge, guidance, and support through your subscription. You might need to reconfigure your firewall and reactivate SELinux. 4.) Reinstall your Java (choose correct package) and Brotli dnf install -y java-11-openjdk-headless brotli 5.) You need to reinstall all programs that are not part of the base and epel repos!!! But fortunately the config is still there. ---
