Are you facing the notorious “libssl.so.1.0.0: cannot open shared object file: No such file or directory” error after upgrading from Ubuntu 18.04 to 20.04? You’re not alone! Many users have encountered this issue when trying to run certain applications, particularly RStudio. But don’t worry, we’ve got you covered! In this blog post, we will walk you through the process of resolving this error, so you don’t have to downgrade to Ubuntu 18.04. Let’s get started!
Understanding the Problem
First, let’s understand what’s causing this error. The issue arises because some applications still depend on the older version of the OpenSSL library (libssl1.0.0), while Ubuntu 20.04 comes with the newer version (libssl1.1). As a result, the application fails to load the required shared library, causing the error.
Step-by-Step Guide to Fix the Error
We’ve compiled a step-by-step guide to help you fix this error. We’ll cover several methods, so you can choose the one that works best for your situation.
Method 1: Install libssl1.0.0 from the Xenial Repository
- Edit the source list by running the following command in your terminal:
sudo nano /etc/apt/sources.list - Add the following line to the file:
deb http://security.ubuntu.com/ubuntu xenial-security main - Save and exit the file, then run:
sudo apt update sudo apt install libssl1.0.0
This method involves adding the Xenial repository, updating the package list, and installing the older version of the OpenSSL library. Keep in mind that installing packages from older Ubuntu releases may cause compatibility issues in the future. Proceed with caution!
Method 2: Download and Install libssl1.0.0 Manually
- Visit the OpenSSL1.0 repository in your browser and download the latest version of libssl1.0.0 for your system. For example, you might download libssl1.0.0_1.0.2n-1ubuntu5.6_amd64.deb.
- Install the downloaded package using the following command:
sudo gdebi ./libssl1.0.0_1.0.2n-1ubuntu5.6_amd64.deb
By downloading and installing the required package manually, you can bypass the package management system and avoid potential compatibility issues with other packages.
Method 3: Install libssl1.0.0 using wget and dpkg
- Download the libssl1.0.0 package using wget:
wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu5.6_amd64.deb - Install the package using dpkg:
sudo dpkg -i libssl1.0.0_1.0.2n-1ubuntu5.6_amd64.deb
This method is similar to the manual installation approach but uses wget and dpkg commands to download and install the package directly from the terminal.
Final Thoughts
By following any of the methods mentioned above, you should be able to fix the “libssl.so.1.0.0: cannot open shared object file: No such file or directory” error on Ubuntu 20.04. Remember that using packages from older releases or installing them manually might introduce potential compatibility issues. It is always advisable to use the latest version of an application and its dependencies when possible.
However, we understand that in some cases, using older libraries or applications is unavoidable. In such scenarios, proceed with caution and ensure that you have a backup of your system to avoid any unforeseen issues.
