Shibboleth can be built on most versions of 32- and 64-bit Linux, but is officially supported only on the following distributions at this time, using the RPM packages available from the project's official mirrors:
Red Hat Enterprise 7/8/9
CentOS 7
Rocky Linux 8/9CentOS 7/8
Amazon Linux 2
Amazon Linux 2023
Packages for CentOS 8 are still being produced but the platform is no longer supported officially due to it having transitioned to an unstable floating package set, and the packages may stop working at any time.
See the SystemRequirements page for more detail on this.
