sudo: apt-get: command not found

This error message is usually encountered when trying to run the apt-get command on a non-Debian based Linux distribution. The apt-get command is used to manage packages on Debian-based Linux systems such as Ubuntu, Debian, and Linux Mint.

If you are using a non-Debian based distribution, you may need to use a different package management tool. For example, on a Red Hat-based distribution like CentOS or Fedora, you would use the yum command instead of apt-get.

If you are using a Debian-based distribution and are still encountering this error message, it may indicate that the package management system is not properly installed or configured. In this case, you may need to reinstall the package management system or troubleshoot the configuration.
