Update Pack 8


Update libpng12-dev first if it is installed

If you have libpng12-dev installed, you need to update it first before proceeding with the upgrade:

apt install libpng12-dev

ATI legacy users: remove the proprietary legacy drivers before the upgrade

UP8 comes with Xorg 1.14 which is not supported by the proprietary legacy drivers (fglrx-legacy-driver). These drivers will stop working after the upgrade. If you use these drivers, it's recommended to remove them and switch to the opensource driver before proceeding with the upgrade.

The following packages need to be removed, if they are installed:

Cinnamon dependencies

If you are using the Cinnamon edition, make sure to install mint-meta-debian-cinnamon. Some dependencies are not explicit between cinnamon packages and missing components might prevent Cinnamon from working corrently.

apt install mint-meta-debian-cinnamon

APT sources handled by MintSources

After the upgrade to UP8 is complete, APT sources are managed by mintsources.

Run mintsources to generate new APT sources for you in /etc/apt/sources.list.d/official-packages-repositories.list


Remove your existing LMDE sources to avoid warnings about duplicated sources:

sudo mv /etc/apt/sources.list /etc/apt/sources.list.bk

You can also remove the software-properties-gtk and mint-debian-mirrors packages, which are no longer needed.

apt remove --purge software-properties-gtk mint-debian-mirrors

Note: MintSources is not compatible with "incoming" or "Debian Testing". It assumes you are following the official LMDE sources. If you use "incoming" or "Debian Testing" on top of LMDE, do not use this tool.

Gnome packages no longer required by Cinnamon

The following packages are no longer needed in the Cinnamon edition:

Update Pack 7


Update Plymouth first

An older version of Plymouth may break the upgrade due to a bug. To avoid this, update Plymouth itself before proceeding with the upgrade:

apt install plymouth

Update debian-system-adjustments first if you have gnome-control-center installed

A bug in debian-system-adjustments older than 2013.09.12.1 may break the upgrade if you have gnome-control-center installed. That means if you have Cinnamon or Gnome Shell.

To avoid it, update debian-system-adjustments before proceeding with the upgrade:

apt install debian-system-adjustments

Warning: Upgrading the Cinnamon edition breaks the screensaver!

Disable the screensaver prior to upgrading to UP7.

In the Cinnamon edition, cinnamon-screensaver replaces and removes gnome-screensaver. If your screensaver activates itself during the upgrade you could get stuck and become unable to unlock your screen. If that happens, drop to console and kill the gnome-screensaver process.

Gnome Shell

Update Pack 7 provides gjs 1.32 which is needed by Cinnamon. Gnome Shell requires gjs 1.36 so it cannot be installed without forcing gjs to upgrade.

You can install Gnome Shell with the following command. Note that this will remove Cinnamon from your system:

apt install -t testing gnome-shell libgjs0c gjs


MintUpdate shows the following message when upgrading packages: "WARNING: The following packages cannot be authenticated!"

This is a cosmetic bug upstream in Debian testing: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=719263

Update Pack 6



If you are using the 64-bit edition of LMDE you need to enable multiarch in order for your system to be able to install and run 32-bit packages (some of which are required for Wine, Picasa, Google Earth and a few other applications).

sudo dpkg --add-architecture i386

Update Pack 3


Multimedia and Security repositories

Starting with Update Pack 3, your APT sources should not point to the Security and Multimedia repositories directly, as these are now part of the Linux Mint Update Pack.

In /etc/apt/sources.list, make sure to replace:

If you're running a recent version of the Update Manager (1.0.4 or later), you will see an error in this window if your repositories aren't configured properly.


The package mint-meta-codecs features an update which should prevent you from experiencing this issue. For information, and in case you are faced with a conflict between gstreamer0.10-plugins-bad and gstreamer0.10-plugins-really-bad, simply remove the gstreamer0.10-plugins-really-bad package. It is maintained by debian-multimedia.org and currently conflicts with the Gstreamer packages maintained by Debian.

nVidia/ATI drivers

Update Pack 3 features the new 3.0 kernel. If you are experiencing issues with the new kernel, you might want to purge and reinstall your drivers. For instance, for the nvidia-glx driver:

apt remove nvidia-kernel-dkms nvidia-glx

then reboot...

apt install nvidia-kernel-dkms nvidia-glx

then reboot again...

CUPS Printers

After updating CUPS, if your printers (or the PDF printer) no longer work, simply launch Menu->Administration->Printing, remove and re-add your printers.

Gnome 3

The Linux Mint theme is now compatible with GTK3 and the issue present in Update Pack 2 is solved.

MESA and nVidia/ATI drivers

If you are using a binary nVidia/ATI driver, be careful when upgrading MESA packages. If the update requires the removal of your driver, ignore it for now and wait for Update Pack 2 to update MESA. In particular, be cautious with the following package updates:
