After installation, reboot the computer. During booting, you will be prompted for the encryption passphrase. Type in the passphrase you specified earlier, then hit Return or Enter key on your keyboard. This illustrates the benefit of encrypting a disk – the system will not boot without the correct passphrase. Just one more layer of physical security for your data.

Were you expecting a graphical login screen? Do not panic. It might seem intimidating (to a new user), but this is actually where the fun starts. If you have never done this before, you are going to be very pleased with yourself when you complete this process. And you will, if you follow the next few steps as suggested. So, log in with your username. Once in, su to root.

The next task is to edit one file. That file is the sources.list file under the /etc/apt directory. It is where you tell the package manager where to install applications from. The objective is to replace the default Debian entries with the default entries you will find on an LMDE installation. It is a very simple text file. To edit it, type nano -w /etc/apt/sources.list. Note: Nano is a very simple, mode-less text editor.

This is what you should see in that file.

And this is the unmodified version of the file in a new installation of LMDE. The task now is to type in each line as it appears below into the file you just opened, and comment out the Debian entries, or just delete them.

When you are finished editing, the file should look just like this one. Save it.

Saving the file should put you back to the command line. Type the following commands to install all necessary applications.

Synchronize the package index files from their sources.
# apt-get update

The system will complain about missing public signing keys. That is expected.

Now, type these commands to import the signing keys that the system complained about.

# apt-key adv --recv-key --keyserver keyserver.ubuntu.com 3EE67F3D0FF405B2

# apt-key adv --recv-key --keyserver keyserver.ubuntu.com 07DC563D1F41B907

Upgrade the system. Not absolutely necessary at this point, but it will not break anything.
# apt-get upgrade

Install core GNOME file, if you want to run a GNOME-based desktop. Every other desktop environment – KDE, LXDE, Xfce – are also available. Your choice, but for this tutorial, I chose to install GNOME.
# apt-get install gnome-core

Install the graphical display package
# apt-get install gdm

This will install all applications installed by default on a new installation of LMDE. Your attention will be needed twice before this command is completed, so do not walk away.
# apt-get install mint-meta-debian

Update: Because of a missing package, the above command will not work. The alternative is to install Mint packages individually. So, instead of the above, use apt-get to install the following:

  • mintupdate
  • mintinstall
  • mintmenu
  • mintsystem
  • mint-artwork-debian
  • mintdesktop
  • linuxmint-keyring
  • mint-flashplugin
  • mint-stylish-addon
  • mintwifi

After logging in, certain applications will still not be installed. Those you will have to install individually by using Synaptic.

Start the graphical display.
# service gdm start

You should get this. Log in …
