Hi @Badis_H,
As @chris noted, Raspberry Pi 4 unfortunately does not meet the CPU microarchitecture requirements for MongoDB 5.0 binary packages. MongoDB 4.4 packages are currently the last supported release series for RPi 4; you also have the option of building from source (ideally cross-compiling in a more capable environment).
Please see Core dump on MongoDB 5.0 on RPi 4 - #13 by Jan-Felix_Abellera for relevant discussion.
Thanks,
Stennie
