/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:

[email protected]:~# 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:

[email protected]:~# 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

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Support for Ubuntu 18.04 was added in Mongo 4.0.6, see https://jira.mongodb.org/browse/SERVER-37778

Unable to start mongod daemon after upgrading OS from Ubuntu 16 to 18

You have version 4.0.4

Method 2

I tried following different options :

Option1: with Ubuntu-16 mongo binaries (before option3 step2); if we are okay with libcurl3

1.  apt-get remove libcurl4
2.  apt-get install libcurl3
3.  able to start the daemon

Option2: didn’t work

1.  apt-get remove libcurl4
2.  apt-get install libcurl4
3.  /etc/init.d/mongo_db7020
/usr/bin/mongod: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by /usr/bin/mongod) 

Option3: copying mongodb 18 binaries worked

1.  apt-get remove libcurl4
2.  rsync -asvh mongoserver:/usr/bin/mongodb-linux-x86_64-ubuntu1804-4.0.4/bin/* /usr/bin/mongodb-linux-x86_64-ubuntu1604-4.0.4/bin
3.  apt-get install libcurl4
4.  able to start the daemon

Option 1 & 3 worked fine for me.

Note: Use and implement method 1 because this method fully tested our system.
