Switching from Debian Stable to Debian Testing with Indonesian Repository

To switch from Debian Stable to Debian Testing and utilize an Indonesian repository, follow these steps:

1. Backup the current sources.list file:

   sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
   

   This creates a backup of your current sources list in case you need to revert to the Stable release.

2. Create a new sources.list:

   sudo echo "deb http://kartolo.sby.datautama.net.id/debian/ testing main contrib non-free" > /etc/apt/sources.list
   

   This command replaces the sources to point to the Testing repository at an Indonesian mirror.

3. Update and upgrade packages:

   sudo apt update && sudo apt upgrade -y && sudo apt dist-upgrade -y
   

   This will update the package list and upgrade your system to Debian Testing. The dist-upgrade command ensures that all dependencies are managed correctly for the Testing branch.

Switching to Testing allows access to newer packages than those in Debian Stable, while using a local repository can improve download speeds and reliability.
