Hello,
I'm experiencing issues running simple `mpirun` commands, after installing
OpenMPI v5.0.3.
When I run any command with `mpirun`, for example:
```
mpirun --help
mpirun --version
mpirun uptime
mpirun hello_c.c
```
I end up with the following error (in every case):
```
--------------------------------------------------------------------------
Sorry! You were supposed to get help about:
prterun-exec-failed
from the file:
/usr/share/openmpi/help-mpirun.txt: No such file or directory
But I couldn't find that topic in the file. Sorry!
--------------------------------------------------------------------------
```
I've installed OpenMPI using these steps:
https://docs.open-mpi.org/en/v5.0.x/installing-open-mpi/quickstart.html
When I install an older version of OpenMPI (such as v4.0.5), I end up with
the following error instead, when running `mpirun`:
```
--------------------------------------------------------------------------
It looks like opal_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
opal_shmem_base_select failed
--> Returned value -1 instead of OPAL_SUCCESS
--------------------------------------------------------------------------
```
You can find all the log files over here:

Love to get some help on this. Thanks.
Best,
