I'm trying to run a binary file but I get:

./binary: error while loading shared libraries: libcrypto.so.3: cannot open shared object file: No such file or directory

I already tried resolving it by installing libssl-dev as said here, or installing openssl (my version is 1.1.1f 31 Mar 2020) as said here.

Both solutions didn't work. Which other solutions I could try to fix it?

Thanks for you help!

    It sounds like binary was not built for Ubuntu 20.04 (which uses libcrypto.so.1.1). Where did you get it, and how did you install it? – steeldriver Apr 03 '23 at 12:47
  • A Google search brings me to this web page. https://stackoverflow.com/questions/71337612/cannot-link-executable-node-library-libcrypto-so-3-not-found It says in a nut shell that the module may not be supported in ANY version. – David Apr 03 '23 at 13:02
  • Thanks for your replies! binary is actually a file for an university assignment. I wanted to solve the issues rather than asking the professor :/ – Francesco Urdih Apr 03 '23 at 13:19

    Well, Ubuntu 22.04 provides libcrypto.so.3 (via package libssl3) so perhaps that is what you should be using? – steeldriver Apr 03 '23 at 13:29
  • Got it, thanks again for your help! – Francesco Urdih Apr 03 '23 at 13:34

Here is a few more options for you:

  1. Check if the library exist with find / -name libcrypto.so.3 if it exist apply this export LD_LIBRARY_PATH=/path/to/lib:$LD_LIBRARY_PATH ( with the good path )

  2. Install the libssl3 package sudo apt-get install libssl3-dev

  3. If that still dont work you can also simply trying reinstalling the library

I solved this by installing OpenSSL libraries by myself.

It uses GNU Autotools.

  1. Download a release from https://github.com/openssl/openssl.
  2. Read https://github.com/openssl/openssl/blob/master/NOTES-UNIX.md, and do Configure.
  3. Then lovely make, then make install.
  4. Do not forget to update your LD_LIBRARY_PATH, also you can add export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:path/to/openssl/installation to .bashrc.
