INFO: Cannot find any server of type <ARCH>
ERROR: No repositories specified, relevant to the target of type <TARGET_ARCH>
The ERROR message indicates that no valid repository (architecture wise) was found for the Patch Analysis Job. Use the RedHatRepositoryManager to build the repository to match your OS and ARCH.
If the repository is valid, however, then there is a mismatch between ARCH and TARGET_ARCH. To resolve the problem set ARCH to TARGET_ARCH in linuxrepo.conf.
However, CentOS 7.x patch support is not there in 8.9.03
centos 7 support was added to the vpc but probably not in the build that you have. i'd suggest opening a support ticket and we can supply the later build.
