error while loading shared libraries:cannot open shared object file: No such file or directory

This error message usually appears when a program is unable to find a required shared library file. This can happen for a variety of reasons, such as:

- The library file is missing or has been deleted.
- The library file is located in a different directory than the one the program is looking in.
- The program does not have permission to access the library file.

To fix this error, you can try the following steps:

1. Check if the required library file is installed on your system. You can do this by running the following command in the terminal:

   $ sudo ldconfig -p | grep <library_name>

Replace `<library_name>` with the name of the library file that the program is looking for. If the library file is not listed, you may need to install it using your system's package manager.

2. Check if the library file is located in the correct directory. Shared library files are typically located in `/usr/lib` or `/usr/local/lib`. You can check if the file is in one of these directories by running the following command in the terminal:

   $ find /usr/lib -name <library_name>

Replace `<library_name>` with the name of the library file. If the file is not in the correct directory, you may need to move it to the correct location.

3. Check if the program has permission to access the library file. Make sure that the file permissions are set correctly and that the program has the necessary permissions to access the file.

If none of these steps work, you may need to reinstall the program or the library file.
