I don't have the library, libcrypto.so.1.1 on my Ubuntu machine. I checked on both, Ubuntu 14.04 and Ubuntu 16.04.
My openSSL version details are:
$ openssl version OpenSSL 1.0.1f 6 Jan 2014
I tried running
apt-get update and then
apt-get install --only-upgrade openssl however it says that openssl is already in the newest version.
It seems that this library does not come by default with the OpenSSL package if installed through Ubuntu repositories.
