When i try to launch the game from terminal.
An error appears saying "error while loading shared libraries:
libcrypto.so.1.0.0: cannot open shared object file: No such file or
directory". I have confirmed that libcrypto.so.1.0.0 is installed on my
system by default.
Hey, I just managed to make it work. Basically, the package has been deprecated and isn't available in any of the repositories that Ubuntu provides, BUT you can add the oldoldstable debian repo to be able to install the lib.
1. Add the new repo in the software sources (the address is at https://packages.debian.org/jessie/i386/libssl1.0.0/download
1.1 You'll get an error saying that it isn't trusted because there's no public key available. Just edit the file /etc/apt/sources.list.d/archive_uri-http_security_debian_org_debian-security-groovy.list. The first line probably looks like "deb http://security.debian.org/debian-security
jessie/updates main". Just add the [trusted=yes] parameter like so "deb [trusted=yes] http://security.debian.org/debian-security
2. Run `sudo apt update`
3. Run `sudo apt install libssl1.0.0`
This should solve your problem. Now, for security sake, I advise that you remove the source that you added or at least disable it, since it's very outdated.
Hope this helps :)
