There are two ways to install Bitmask – via the stand-alone bundles or via packages.

Download stand-alone bundle

64 bit kernel

Download 64 bit

Signature file

32 bit kernel

Download 32 bit

Signature file

If you want to make sure that the Bitmask wasn’t messed with during download
you can authenticate the signature.

How do you tell if you running a 32 bit or 64 bit kernel? Run the following command:

uname -m

If the result is:

• x86_64, you have 64 bit
• i686, you have 32 bit
• i386, you have 32 bit

NOTE:
Stand-alone bundles are useful if want to run Bitmask from a thumb drive. Or from a distribution which we don’t support with packages.
There are two disadvantages to the stand-alone bundle:

• The Bitmask app will be less well integrated with the desktop environment.
• Running from the bundle is slower to start than via packages.

Install as packages

This is the recommended method of installing Bitmask. If installed as a package, Bitmask will run faster, be better integrated in the system, and will be kept up to date.

Ubuntu 15.10 (Wily Werewolf)

To install

sudo -s
add-apt-repository "deb http://deb.bitmask.net/debian wily main"
wget -O- https://dl.bitmask.net/apt.key | apt-key add -
apt-get update
apt-get install bitmask leap-keyring

To remove

sudo -s
apt-get remove bitmask leap-keyring
apt-key del 0x1E34A1828E207901
add-apt-repository --remove "deb http://deb.bitmask.net/debian wily main"

Ubuntu 15.04 (Vivid Vervet)

To install

sudo -s
add-apt-repository "deb http://deb.bitmask.net/debian vivid main"
wget -O- https://dl.bitmask.net/apt.key | apt-key add -
apt-get update
apt-get install bitmask leap-keyring

To remove

sudo -s
apt-get remove bitmask leap-keyring
apt-key del 0x1E34A1828E207901
add-apt-repository --remove "deb http://deb.bitmask.net/debian vivid main"

Debian 8.0 (Jessie)

To install

sudo -s
echo "deb http://deb.bitmask.net/debian jessie main" > /etc/apt/sources.list.d/bitmask.list
wget -O- https://dl.bitmask.net/apt.key | apt-key add -
apt-get update
apt-get install bitmask leap-keyring

To remove

sudo -s
apt-get remove bitmask leap-keyring
apt-key del 0x1E34A1828E207901
rm /etc/apt/sources.list.d/bitmask.list

Upgrading

From stand-alone bundles: Bitmask should upgrade itself automatically (for versions equal or later than 0.7.0). If you are running a version prior to 0.7.0, you can download the new bundle and copy the “config” folder from the old bundle directory.

From packages: If you are running from packages, then you can trigger an update like so:

apt-get update
apt-get dist-upgrade

NOTE: When upgrading Ubuntu from 14.10 (Utopic) to 15.04 (Vivid), you may need to run this command again:

sudo add-apt-repository "deb deb.bitmask.net/debian vivid main"

Similar is needed for the upgrade from 15.04 to 15.10 (Wily):

sudo add-apt-repository "deb deb.bitmask.net/debian wily main"

This is because the Ubuntu upgrade process probably commented out all your prior custom repository lines in /etc/apt/sources.list.
