How To Fix “error loading shared libraries: libssl.so.1.0.0” on Ubuntu

Ubuntu 8

In the world of Ubuntu, encountering error messages is not uncommon. One such error, “error loading shared libraries: libssl.so.1.0.0”, can cause various applications to fail to launch. This article will guide you through the process of resolving this issue, ensuring your Ubuntu system runs smoothly.

Understanding the Error

Before we delve into the solution, it’s crucial to understand what the error message means. The error “error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory” indicates that the system is unable to find the libssl.so.1.0.0 library. This library is part of the OpenSSL project’s implementation of the SSL and TLS cryptographic protocols and is essential for many applications.

Step 1: Checking if the Package is Installed

The first step in resolving this issue is to check if the libssl1.0.0 package is installed on your system. You can do this by running the following command in your terminal:

sudo apt-get install libssl1.0.0:amd64

Here, sudo is a command that allows you to run programs with the security privileges of another user (by default, the superuser). apt-get is the package handling utility in Ubuntu, install is the command to install a new package, and libssl1.0.0:amd64 is the package you want to install.

If the package is already installed, you will see a message indicating this. If not, the system will install it for you.

Step 2: Verifying the Location of the Library

The libssl.so.1.0.0 library should be located at /lib/x86_64-linux-gnu/libssl.so.1.0.0 with a symbolic link at /usr/lib/x86_64-linux-gnu/libssl.so. If the library is missing or the symbolic link is broken, you can try reinstalling the package using the --reinstall flag:

sudo apt-get --reinstall install libssl1.0.0:amd64

The --reinstall flag tells apt-get to reinstall the package, even if it’s already installed. This can help fix any issues with the package’s installation.

Step 3: Manually Creating the Symbolic Link

If the above steps do not resolve the issue, you can try manually creating the symbolic link. This can be done using the ln command, which creates links between files. Run the following command:

sudo ln -s /lib/x86_64-linux-gnu/libssl.so.1.0.0 /usr/lib/x86_64-linux-gnu/libssl.so

Here, -s creates a symbolic link, /lib/x86_64-linux-gnu/libssl.so.1.0.0 is the target file (the file the link points to), and /usr/lib/x86_64-linux-gnu/libssl.so is the name of the link.

Step 4: Refer to External Sources

If you are unable to find the libssl1.0.0 package in your sources, you may need to refer to external sources or repositories. You can check the Ask Ubuntu post here for more information on installing software from unsupported releases.

Conclusion

It’s worth noting that the lack of a symlink for libssl.so.1.0.0 could potentially be a bug in the OpenSSL package or another related package. If the steps above do not resolve your issue, it may be worth reaching out to the Ubuntu community or the OpenSSL project for further assistance. With the right approach and a bit of patience, you should be able to resolve the “error loading shared libraries: libssl.so.1.0.0” error and get your Ubuntu system back on track.
