  You should be able to run `yum update -y` that will update Zimbra for you. In addition we do support Rocky Linux, you can find that build on our Downloads page.

Is there a way to manually install the patch? My yum on old Centos 6.10 goes up to 8.8.15 patch 28 and reports nothing new. I admit I had issues wit yum and this may be the cause, but is there a way to do the update in a manual manner?

thank you

  Zimbra 8.8.15 on CentOS 6 should still update to the latest patch see https://wiki.zimbra.com/wiki/Zimbra_Releases/8.8.15/P32
  
  If it does not work, CentOS 6 is very old and Zimbra already marks this release as deprecated. Please consider moving to a newer OS version using https://wiki.zimbra.com/wiki/Zimbra_Suite_Plus/Zimbra_Backup_Plus/Incremental_migration_with_Zimbra_Backup_Plus
