root@dummy2:~# /usr/bin/mongod --config /etc/mongo/db8303/mongodb.conf &
/usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by /usr/bin/mongod)

The difference that I'm seeing before and after OS upgrade on libcurl version:

before:

root@dummy2:~# ls -lrt /usr/lib/x86_64-linux-gnu/libcurl*
/usr/lib/x86_64-linux-gnu/libcurl.so.4 -> libcurl.so.4.4.0
/usr/lib/x86_64-linux-gnu/libcurl.so.3 -> libcurl.so.4
/usr/lib/x86_64-linux-gnu/libcurl-gnutls.so.4 -> libcurl-gnutls.so.4.4.0
/usr/lib/x86_64-linux-gnu/libcurl-gnutls.so.3 -> libcurl-gnutls.so.4
/usr/lib/x86_64-linux-gnu/libcurl.so.4.4.0
/usr/lib/x86_64-linux-gnu/libcurl-gnutls.so.4.4.0

After:

root@dummy2:~# ls -lrt /usr/lib/x86_64-linux-gnu/libcurl
/usr/lib/x86_64-linux-gnu/libcurl.so.4 -> libcurl.so.4.5.0
/usr/lib/x86_64-linux-gnu/libcurl-gnutls.so.4 -> libcurl-gnutls.so.4.5.0
/usr/lib/x86_64-linux-gnu/libcurl-gnutls.so.3 -> libcurl-gnutls.so.4
/usr/lib/x86_64-linux-gnu/libcurl.so.4.5.0
/usr/lib/x86_64-linux-gnu/libcurl-gnutls.so.4.5.0
