Hello, i solved a similar problem following these steps in the command line:
-install wget, if not yet installed:

sudo apt install wget

-install the following package:

wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1l-1ubuntu1.3_amd64.deb

-install the package:

sudo dpkg -i libssl1.1_1.1.1l-1ubuntu1.3_amd64.deb
