Plesk installation issue on AlmaLinux 9.6 is due to missing dependencies

The error you’re encountering during Plesk installation on AlmaLinux 9.6 is due to missing dependencies, especially:

• libidn.so.12

• libluajit-5.1.so.2

• libaspell.so.15

• perl-JSON-XS

• sharutils

• libbsd.so.0

• liblqr-1.so.0

• libraqm.so.0

• libmilter.so.1.0

• libavif.so.15

⚠️ Why this is happening

AlmaLinux 9.6 likely ships newer versions or omits legacy libraries Plesk 18.0.70 still depends on. Some of these are deprecated or moved to optional/epel repositories.

Recommended Solution (Safe)

1. Switch to AlmaLinux 8.9 or 9.2, which is officially tested and supported by Plesk [as of version 18.0.70].

   • AlmaLinux 9.6 is too new, and the Plesk repo likely hasn’t caught up yet with rebuilt packages for it.

   If you must use AlmaLinux 9.6, see the workaround below — but stability is not guaranteed.

🧪 Workaround (Advanced / Not Officially Recommended)

Only do this if you’re testing or have no option to downgrade the OS.

1. Enable EPEL and CodeReady Builder
