LibreOffice error while loading shared libraries: libssl3.so:

This error message indicates that the libssl3.so library file required by LibreOffice is missing or not found in the system. This library file is a part of the OpenSSL library, which is used for secure communication over the internet.

To resolve this issue, you can try the following steps:

1. Check if the openssl package is installed on your system. You can use the following command to check:

   dpkg -l | grep openssl

If it is not installed, you can install it using the following command:

   sudo apt-get install openssl

2. Check if the libssl3.so library file exists on your system. You can use the following command to search for it:

   sudo find / -name libssl3.so

If it is not found, you can try reinstalling the OpenSSL library using the following command:

   sudo apt-get install --reinstall libssl-dev

3. If the above steps do not resolve the issue, you can try updating your system and installing the latest version of LibreOffice.

   sudo apt-get update
   sudo apt-get install libreoffice

This will update all the required libraries and dependencies and may resolve the issue.
