OpenSSL error when starting Mongosh

Ops and Admin Installation & Upgrades
3

Instead of mongodb-mongosh, try installing mongodb-mongosh-shared-openssl3
or mongodb-mongosh-shared-openssl11 that fits for your running environment.

For Amazon Linux 2023 where OpenSSL v3 is bundled with, it solved the problem:

$ # This will do
$ dnf install -qy mongodb-mongosh-shared-openssl3

Installed:
  mongodb-mongosh-shared-openssl3-2.0.0-1.el8.aarch64

$ if `mongosh --help 1>/dev/null`; then echo 'OK'; else echo '!!!NG!!!'; fi
OK

$ # This WILL NOT do
$ dnf install -qy mongodb-mongosh

Installed:
  mongodb-mongosh-2.0.0-1.el8.aarch64

$ if `mongosh --help 1>/dev/null`; then echo 'OK'; else echo '!!!NG!!!'; fi
mongosh: OpenSSL configuration error:
20B0BFA4FFFF0000:error:030000A9:digital envelope routines:alg_module_init:unknown option:../deps/openssl/openssl/crypto/evp/evp_cnf.c:61:name=rh-allow-sha1-signatures, value=yes


!!!NG!!!
$ dnf erase -qy mongodb-mongosh

Removed:
  mongodb-mongosh-2.0.0-1.el8.aarch64
