How to resolve the issue of being unable to find the command in Ubuntu using apt-get?

If the apt-get command is not found in Ubuntu, it may be because your system does not have the apt package manager installed. You can try using the following command to install apt:

sudo apt update
sudo apt install apt

After the installation is complete, you should be able to use the apt-get command again. If the issue persists, it may be due to a problem with the software source configuration in the system. You can try updating the software source configuration file and then try using the apt-get command again.

sudo apt update

If the issue persists, there may be other problems within the system. It is recommended to try restarting the system or checking the system logs for more information.
