The intent of producing PPA packages from the libmongocrypt waterfall is that we provide packages for all of the same os/arch combinations for which the server also produces PPA packages. This enables users to install libmongocrypt wherever the mongocryptd/crypt_shared (the necessary query analysis component produced by the server) is supported.

While working on MONGOCRYPT-579 it became apparent that certain os/arch combinations are not producing libmongocrypt packages (i.e., missing tasks and/or build variants).

The following os/arch combinations should be added/updated as needed in the libmongocrypt Evergreen configuration so that they produce PPA packages:

• RHEL8 (x64, arm64, power, zseries)
• RHEL9 (x64, arm64)
