Known Issues
Custom replacements of default repositories
This script expects the original repository configuration being present, as well
as enabled (i.e. for CentOS the baseos
repo configuration in the
/etc/yum.repos.d/CentOS-Linux-BaseOS.repo
file has to be present and enabled).
Also make sure that there are no other repositories which could interfere with the
original configuration.
Any distribution that has had its core repositories altered, removed, duplicated or overridden may cause migrate2rocky to break or corrupt the system when run. Any attempt to migrate such systems, even after reversing the changes made by such software, is not supported in any way. In all cases you should backup your system before using migrate2rocky and USE AT YOUR OWN RISK.
This especially happens on systems configured with a centralized package management like Katello (RedHat Satellite 6) or Uyuni (RedHat Satellite 5, SUSE Manager).
RHEL migrations show error messages during conversion
Installing : rocky-release-8.3-13.el8.noarch 2/5Error unpacking rpm package rocky-release-8.3-13.el8.noarch
...
error: unpacking of archive failed on file /usr/share/redhat-release: cpio: File from package already exists as a directory in system
error: rocky-release-8.3-13.el8.noarch: install failed
...
Error: Transaction failed
This results from conflicts in the directory structure of RHEL with that of RockyLinux. migrate2rocky will detect the issue and go on to remove the conflicting directory and install rocky-release with the rpm command.
Grub still shows kernel entries from previous installation
This is normal. The running kernel cannot be safely removed when migrate2rocky is run. The RockyLinux kernel should come up as the default highlighed kernel on reboot but the other ones will remain until they are removed or replaced by newer kernels. If you want you can manually remove the old kernels after reboot with dnf or rpm.
