Disable Local Repositories

If you have the USB flash drive we created to install Debian plugged into the USB port, Debian may default to installing software from this local repository.

A "repository" is the location that your software manager searches for available software.

Using the repository on your USB flash drive as the default may cause errors when trying to install software that is not locally available.

In order to disable it, we need to open the Synaptic Package Manager. This program is a visual interface for installing software and managing repositories that is available by default on Debian.

When we open it from the Start Menu in the bottom right and navigate to "Administration", and then the program "Synaptic Package Manager".

Opening this program will ask us to end the password for the root user account that we created during the Debian installation process.

You will need to enter your account password.

Once you do that, the system may request to update your repository because it is out of date. This will ensure that you are installing the most up-to-date software.
