apt error while loading shared libraries libapt-pkgso60 cannot open sh

This error usually occurs when the system is unable to locate or load the shared library "libapt-pkg.so.6.0" required by the apt package manager.

Here are a few steps you can try to resolve this issue:

Check if the library is installed: Run the following command to check if the library is present on your system:
```
ls -l /usr/lib/x86_64-linux-gnu/libapt-pkg.so.6.0
```
If the library is not found, you might need to reinstall the apt package. You can do this by running the following command:
```
sudo apt-get install --reinstall apt
```
Update the library cache: Run the following command to update the library cache and rebuild it:
```
sudo ldconfig
```
Check for any conflicting packages: If you have recently installed or updated any packages, there might be a conflict with the apt package. Try removing or downgrading the conflicting package and then reinstalling the apt package.
Reinstall the libapt-pkg package: If none of the above steps work, you can try reinstalling the libapt-pkg package. Run the following command to reinstall it:
```
sudo apt-get install --reinstall libapt-pkg6.0
```

If none of these solutions work, there might be a deeper issue with your system. In such cases, it might be necessary to seek further assistance from your system administrator or consider reinstalling the operating system
