Not only the Virtual Appliance still relies on CentOS 7. We want to migrate our CentOS 7 based Linux server to a newer operating system, but for the current ESET Protect version (11) only Debian 10 (outdated) and CentOS 7 (soon outdated) seem to be supported. At least these are the only operating systems besides SLES with an installation manual: https://help.eset.com/protect_install/11.0/en-US/installation_linux.html
How is it possible that a new software is released and all manuals rely to old operating systems?
