Error: Timeout was reached Reading package lists... Done

This error message usually indicates a problem with the internet connection or the server that the package lists are being downloaded from.

Here are a few steps you can take to troubleshoot this error:

1. Check your internet connection: Make sure your device is connected to the internet and that the connection is stable. Try opening a web browser and loading a website to see if you can access the internet.

2. Update your package manager: Run the command `sudo apt-get update` to update your package manager. This will refresh the package lists and may resolve the issue.

3. Try a different server: Sometimes the server that you are downloading package lists from may be experiencing issues. Try switching to a different server by running the command `sudo apt-get update --fix-missing`.

4. Check for proxy settings: If you are behind a proxy, make sure the proxy settings are correctly configured in your system. You can check the settings by running the command `env | grep -i proxy`.

5. Wait and try again later: If none of the above steps work, the issue may be with the server that you are trying to download the package lists from. Wait for a few hours and try again later.
