Hi @Sam_Quinn
From recent post signal=ILL seems to be related to unsupported cpu architectures. What CPU are you running ?
Changes to supported microarchitecture
See MongoDB 5.0 CPU Intel G4650 compatibility - #2 by Stennie for more details and a solution 5.0 by building your own.
If you don’t want the packaged install you can download and install from tarball.. This does not change the requirement for a supported platfrom.
