Hi @cong3232
Alibaba linux is not in the list of supported systems so that is why percona-release script reports that the repository is not supported on this system.
We build and test our software products on Red Hat Enterprise Linux (RHEL), Debian Linux and Ubuntu Server LTS releases (RHEL-compatible derivative Linux distributions like AlmaLinux, CentOS, Oracle Linux or Rocky Linux may also work, but we do not actively test our binaries on these platforms).
You can try to download and install packages directly from the repo or from website.
