Parallel run in Ubuntu 22.04

We seem to have problems running applications in parallel in Ubuntu 22.04. For instance, the motorBike tutorial displays the following error:

--> FOAM FATAL ERROR: (openfoam-2112 patch=220610) attempt to run parallel on 1 processor

From static bool Foam::UPstream::init(int&, char**&, bool)
in file UPstream.C at line 297.
