Wickr is non-free software. Discouraged as per Avoid nonfree software!

This can lead to breaking the package upgrading system! This is because we are mixing Debian (which Whonix ™ is based on) with Ubuntu software sources. [1]

This is counter to best practices on the Install Software page. Therefore use a separate Whonix-Workstation ™.

Open Terminal[edit]

Open a terminal.

If you are using Qubes-Whonix ™, complete the following steps.

Qubes App Launcher (blue/grey "Q")Whonix-Workstation ™ AppVM (commonly named anon-whonix)Xfce Terminal

If you are using a graphical Whonix with XFCE, run.

Start MenuXfce Terminal

APT Signing Key[edit]

Add Ubuntu's apt signing key.

Whonix first time users warning Warning:

The following command using gpg with --recv-keys either does no longer work or should not be used for security reasons. [2] The OpenPGP public key should be downloaded from the web instead. See also Secure Downloads. This is currently undocumented. This is not a Whonix ™ issue. It can be resolved as per Free Support Principle. Contributions to documentation are happily considered.

sudo apt-key --keyring /etc/apt/trusted.gpg.d/ubuntu.gpg adv --keyserver hkp://qdigse2yzvuglcix.onion --recv-keys 630239CC130E1A7FD81A27B140976EAF437D05B5

Expected output.

Executing: /tmp/apt-key-gpghome.6Ouq0wKoVF/ --keyserver hkp://qdigse2yzvuglcix.onion --recv-keys 630239CC130E1A7FD81A27B140976EAF437D05B5
key 40976EAF437D05B5:
59 signatures not checked due to missing keys
gpg: key 40976EAF437D05B5: public key "Ubuntu Archive Automatic Signing Key <>" imported
gpg: Total number processed: 1
gpg:               imported: 1

The warning 59 signatures not checked due to missing keys can be safely ignored if you checked validity of the key fingerprint 630239CC130E1A7FD81A27B140976EAF437D05B5 being the Ubuntu repository fingerprint. [3]

APT Sources[edit]

[4] [5]

A new file /etc/apt/sources.list.d/ubuntu.list containing the Ubuntu repository has to be created.

Open file /etc/apt/sources.list.d/ubuntu.list in an editor with root rights.

(Qubes-Whonix ™: In TemplateVM)

This box uses sudoedit for better security. This is an example. Other tools could archive the same goal too. If this example does not work for you or if you are not using Whonix, please see this link.

sudoedit /etc/apt/sources.list.d/ubuntu.list

Update the package lists.

sudo apt-get update

Install dependencies.

sudo apt-get install libhunspell-1.3 libprotobuf9v5 libpng12-0


Ambox warning pn.svg.png Manual Software Installation Warning

Manual installation of software packages should be avoided even from a trusted source. Reasons:

See: How to Install Software Safely for more details.

Download WickrMe from Choose the Ubuntu version. [6]

Save in ~/Downloads folder. (Hint Tor Browser#Navigating Tor Browser Downloads.)

At the time of writing, no software signatures were provided.

Change Directory[edit]

Change to Downloads folder.

cd ~/Downloads



unzip WickrMe*.zip


Install WickrQt. [7]

sudo dpkg -i wickr-qt_*_amd64.deb

Install WickrMe.

sudo dpkg -i WickrMe_*_amd64.deb


Fix dependencies.

sudo apt-get install -f

Download libgstreamer-plugins-good1.0-0.

apt-get download libgstreamer-plugins-good1.0-0

Fix packaging conflict (since we mix with Ubuntu).

sudo dpkg --force-all --install libgstreamer-plugins-good*_amd64.deb

Fix dependencies.

sudo apt-get install -f

Last lines of output are expected to show something like:

Setting up wickrme (4.59.10-01) ...
Processing triggers for libc-bin (2.24-11+deb9u3) ...


The installation process is now complete.



Forum Discussion[edit]


  1. For better stability would to provide Debian downloads or even better an apt repository for Debian.
  3. This is because gpg home folder /etc/apt/trusted.gpg.d does not know any signatures of any signatories who signed that key.
  4. Created using
  5. says Ubuntu 16.04 which is xenial.
  6. Replaced gdebi with dpkg. It's just a deb. Dpkg should be very very much fine. Even easier to debug than graphical frontend gdebi.
