I want to use OpenSSL1.1.1 version for my code development. Currently I am working with Openssl 1.1.0g on Ubuntu 18.04 machine.

If I download the package with the command sudo apt install libssl-dev, then I get OpenSSL 1.1.0g version,

If I download the package with the command sudo apt install libssl1.0-dev, then I get OpenSSL 1.0.2n version,

How do I download the OpenSSL 1.1.0 and libssl package?

Note: I don't want to download OpenSSL package separately and build it externally. I am supposed to download using an Ubuntu package.

In fact your question was duplicate and the same question already appeared in Upgrade openssl 1.1.0 to 1.1.1 in Ubuntu 18.04.

As already answered by @Kevin Bowen, openssl 1.1.1 is not in the current Ubuntu repositories, you will need to download, compile, and install the latest OpenSSL version manually.

The same thing I too suggested in the beginning in comments section. My favorite is always to install in /opt, so I suggested that too in comments section.

If you don't want to do, then you will be stuck for ever!

Guide to install openssl 1.1.1b on Ubuntu 18.04.

Step 1 : Download openssl 1.1.1b

Download the latest openssl 1.1.1b release from from Ubuntu source package….

OpenSSL Cryptography and SSL/TLS Toolkit

Figure-1: Download openssl 1.1.1b

You can also easily install openssl 1.1.1b package by running the commands below…

wget
https://www.openssl.org/source/openssl-1.1.1b.tar.gz

Step 2 : Install Openssl from the tar.gb package

Now create /opt/openssl directory:

$ sudo mkdir /opt/openssl
Figure-2: Create folder for openssl under /opt directory.

Now that you’ve downloaded the correct archive package for your system into ~/Downloads folder, run the following commands to install Openssl.

$ sudo tar xfvz ~/Downloads/openssl-1.1.1b.tar.gz --directory /opt/openssl

Figure-3: Extraction into /opt/openssl is complete.

$ perl --version
Figure-4: Perl version.

Export LD_LIBRARY_PATH environment variable with the following value:

$ export LD_LIBRARY_PATH=/opt/openssl/lib

Verify that LD_LIBRARY_PATH is set with correct value by this command:

$ echo $LD_LIBRARY_PATH

Figure-5: Value of environment variable LD_LIBRARY_PATH is /opt/openssl/lib.

Issue the config commands:

 $ cd /opt/openssl/openssl-1.1.1b

 $ sudo ./config –prefix=/opt/openssl –openssldir=/opt/openssl/ssl

Figure-6: config command

Next, issue make command:

$ sudo make

Issue make test command to check for possible errors:

$ sudo make test

Figure-7: All tests successful.

Issue make install commands:

$ sudo make install

Where is openssl binary being located?

Issue the following commands:

$ sudo updatedb                              # rebuild library cache

$ locate openssl | grep /opt/openssl/bin

Figure-8: Locate openssl binary.

The directory /usr/bin has openssl binary which is an earler version. The presence of this unwanted openssl binary /usr/bin/openssl is going to cause us trouble, so we have to check this!

Issue the following commands in order to tackle /usr/bin/openssl binary:

$ cd /usr/bin

$ ls -l openssl

$ sudo mv openssl openssl.old       # rename earlier version openssl to openssl.old

Figure-9: Rename earlier version of openssl binary to openssl.old.

Step 3 : Setup PATH environment variable

Openssl needs to set PATH environment variables which is to be set as shown below.

Create a file called openssl.sh under /etc/profile.d/ directory.

$ sudo touch /etc/profile.d/openssl.sh

$ sudo vi /etc/profile.d/openssl.sh

Add the following contents:

#!/bin/sh

export PATH=/opt/openssl/bin:${PATH}

Save and close the file. Make it executable using the following command.

$ sudo chmod +x /etc/profile.d/openssl.sh

Then, set the environment variables permanently by running the following command:

 $ source /etc/profile.d/openssl.sh

Log out or reboot your system.

Now, check the openssl version using command:

$ openssl version

Figure-10: openssl binary version.

Now, check the PATH environment variable:

$ echo $PATH

Summary:

This method downloads, extracts, compiles, and installs the latest OpenSSL version 1.1.1b manually.
