I’m encountering an issue on Ubuntu 20.04 where an application is failing to start due to a problem with a shared library, specifically “libcrypto.so.3”. How can I resolve this error and get my application running again?

I’m running into a bit of a snag on my Ubuntu 20.04 setup, and I could really use some help. So here’s the deal: I was trying to launch this application I’ve been using without any issues, and suddenly it won’t start. It throws an error related to a shared library—specifically “libcrypto.so.3”. Honestly, I have no idea why this popped up out of nowhere, and I’m not sure what to do about it.

I read through the console output, and it clearly points to libcrypto, but beyond that, I’m pretty lost. I tried updating everything using the usual `sudo apt update` and `sudo apt upgrade` commands, thinking maybe it would fix any underlying issues, but no luck. The app just continues to crash with the same error.

I’ve done a bit of digging and found that libcrypto is part of the OpenSSL package, which made me wonder if there might be a version mismatch or something. I even checked my installed versions of OpenSSL, and everything seems fine, but I can’t shake the feeling that there’s something I’ve overlooked.

Has anyone else faced this issue before? If so, what did you do to get your application back up and running? Should I consider reinstalling OpenSSL, or is there a specific command I can use to fix this shared library?

I’ve tried searching online solutions, but most of the threads I found were outdated or didn’t specifically address my version of Ubuntu. I just want to make sure that I’m not breaking anything further when trying to fix it. It’s frustrating, and I really need this application to work again.

Any tips, tricks, or specific commands would be greatly appreciated! I would be eternally grateful if someone could help me out of this bind. Thanks in advance for any insights!

    1. Help with libcrypto.so.3 Error on Ubuntu 20.04


      I totally get your frustration! That “libcrypto.so.3” error can be a real pain. It sounds like you might be dealing with a library version issue, which is a common thing when working with shared libraries.

      Here are some troubleshooting steps you might want to consider:

      • Check if the libcrypto.so.3 file is actually present. You can do this by running:
        ls /usr/lib/x86_64-linux-gnu/libcrypto.so.3
      • If it’s not there, or if you suspect it’s corrupted, you might want to reinstall the OpenSSL package. You can do that with:
        sudo apt-get install –reinstall libssl-dev
      • Sometimes, it helps to clear out the cache and re-install the dependencies. You could try:
        sudo apt-get autoremove
        sudo apt-get clean
        sudo apt-get install -f
      • If that still doesn’t work, you might have to manually link the library. Use:
        sudo ldconfig

        After installing or reinstalling any library, this will refresh the cached links.

      • Lastly, check if the application has any specific version requirements for OpenSSL. If it needs an older or newer version, you might need to manage multiple versions using something like update-alternatives.

      Remember to back up any important data before making major changes. If you’re still having trouble after trying these steps, don’t hesitate to ask in forums or communities that focus on Ubuntu or the specific application you’re using. There might be someone who’s run into the same issue!

      Good luck, and I hope you can get your app up and running again!



    2. It seems like you’re encountering a common issue related to the OpenSSL library, specifically with the `libcrypto.so.3` shared library. Since you’ve tried updating your packages without success, there are a few steps you can take to troubleshoot further. First, you should check if the appropriate version of OpenSSL is installed and that `libcrypto.so.3` is correctly linked. You can do this by using the command ldconfig -p | grep libcrypto to see what versions are currently available on your system. If the library isn’t listed, or if you notice a version mismatch, you may need to install or reinstall OpenSSL. Use the command sudo apt install --reinstall openssl libssl-dev to ensure you have the latest version and the necessary development files.

      If the library issues persist even after reinstalling OpenSSL, you might need to manually link the library to the correct location. You can do this by creating a symbolic link to the expected library version. For example, if your application is looking for `libcrypto.so.3` and you have a different version installed, create a symlink using sudo ln -s /usr/lib/x86_64-linux-gnu/libcrypto.so.x /usr/lib/x86_64-linux-gnu/libcrypto.so.3, replacing libcrypto.so.x with the actual version you have. Additionally, verify if your application requires a specific version of OpenSSL by checking its documentation or the website of the application for compatibility notes. Proceeding with these steps should help you troubleshoot and ultimately resolve the issue with your application.
