unsupport OS - almalinux 9.3

Almalinux 9.3 - apiscp wont install, errors that it is an unsuport OS? Install instructions dont mention what version is or not - can you advise please?

Presently unsupported. There are package rebuilds that need to be completed, including Pagespeed, which went dormant earlier this year.

No ETA, although RHEL8 will not reach EOL until 2029.

Is there a replacement for mod_pagespeed?

Maybe there could be a RH9 version with reduced features. I’ve got no idea what to do with retired software that lacks replacement. I mean this will be a problem for RH8 too if a major error occures because for things like pagespeed there hasn’t been serious development for a while already (and now non anymore).
