Install Cryptomator Last updated: 2022.04.25

Overview

Debian 11, Debian 10, Debian 9

Ubuntu 20.04, Ubuntu 18.04

Cryptomator is an excellent tool to apply client-side AES encryption to files you plan on storing on a cloud provider. Crpytomater works with any cloud storage provider, but you will have the best experience with one that has a Linux sync client (e.g. Dropbox). This bit will cover two available methods for installing Cryptomator, via PPA repository and via AppImage.

Install Via PPA

Not all applications, or versions of an application, are available from the official Debian / Ubuntu repositories. A Personal Package Archive (PPA) repository can be added to your system sources, allowing you to still install and update application releases with the apt package manager.

Verify that you have the software-properties-common package installed on your system. This is required for the included add-apt-repository utility.

sudo apt install software-properties-common

Add the Cryptomator PPA to your system sources.

sudo add-apt-repository ppa:sebastian-stenzel/cryptomator

Update your system repositories, you will see the Cryptomator PPA in the list of updated sources.

sudo apt update

Finally, install the Cryptomator application.

sudo apt install cryptomator

Install Via AppImage

Cryptomator can be installed via an AppImage package. AppImage is a portable package system that alllows applications to be easily distributed to a range of different systems; it also does not require administrative permissions.

Download AppImage

Create a new directory for Cryptomator to be installed in. We will put this directory in ~/Applications/ as is recommended in the AppImage documentation, but you may choose any location you wish.

mkdir -p ~/Applications/cryptomator

Download the Cryptomator AppImage to the ~/Applications/cryptomator/ directory. At the time of writing this was version 1.6.5. Check the Cryptomator release page for the most recent version.

wget https://github.com/cryptomator/cryptomator/releases/download/1.6.5/cryptomator-1.6.5-x86_64.AppImage -P ~/Applications/cryptomator/

Rename the downloaded AppImage so it can be easily referenced later.

mv ~/Applications/cryptomator/cryptomator-1.6.5-x86_64.AppImage ~/Applications/cryptomator/cryptomator.AppImage

Make the downloaded AppImage file executable.

chmod a+x ~/Applications/cryptomator/cryptomator.AppImage

The Cryptomator AppImage is now ready to go! Launch it via your file explorer or terminal.

Create Desktop Entry

For the application to be accessible in the same fashion as apt installed applications, you will have to create a desktop entry on your system.

Before creating the desktop entry, we will fetch ourselves a launcher icon to use for Cryptomator. Store this icon in the same directory as the AppImage, ~/Applications/cryptomator/ in this case.

wget https://cryptomator.org/presskit/cryptomator-logo.png -O ~/Applications/cryptomator/cryptomator.png

Using your editor of choice, create a new file named cryptomator.desktop in the ~/.local/share/applications/ directory.

nano ~/.local/share/applications/cryptomator.desktop

Enter the following, replacing USERNAME with your system username. If you are using a different path also apply that here.

[Desktop Entry]
Name=Cryptomator
Exec=/home/USERNAME/Applications/cryptomator/cryptomator.AppImage
Icon=/home/USERNAME/Applications/cryptomator/cryptomator.png
Type=Application
StartupNotify=true
MimeType=application;

That’s all there is to it, you should now see Cryptomator listed in your system application list.

Conclusion

Cryptomator has now been successfully installed. Launch the application and you’ll be greeted by their friendly robot mascot, and a to-be populated list of your encrypted vaults. Rest easy knowing your data is encrypted before being sent off to the cloud. Take a gander at the Cryptomator documentation for complete details on what you can do with vaults.
