How to Install and Configure Kasm Workspaces on Ubuntu


As we would like to test the suspicious URL, we could set up a virtual machine and create a snapshot and test that way. Once it has been done, then roll back the snapshot. The problem with this approach is that sometimes you forget to roll back the snapshot and are not sure about the status of that machine.


Kasm Workspaces provides a safe way to browse websites, check webmail and open files without putting the computer at risk. Kasm environments isolate users by creating a chasm between users’ computers and web threats.

Here’s the step-by-step.

Our Environment

  • We utilised Microsoft Azure to create a dedicated virtual machine with Standard B2s size, 2 vCPUs, and 4 Gb RAM. We used a 64 GB OS disk. We allowed 443 and SSH ports only.
  • For simplicity, we use a single-server installation approach


Ensure to follow the requirement based on this Kasm documentation.

Supported OS: Ubuntu 18.04 / 20.04 / 22.04 (amd64/arm64)
Minimum Requirement: 2 cores CPU, 4GB Memory, 50GB storage 
We had an issue with installation initially – “Not enough disk space for the installation – Please free up disk space or use -I to not present images“. It turned out our disk has 30 GB on Microsoft Azure. Once we increased to 64 GB, the installation is good.

Open the command line or terminal.

Log in to the virtual machine.

Creating A Swap Partition

We use the recommendation which is a 1GB swap partition.

sudo dd if=/dev/zero bs=1M count=1024 of=/mnt/1GiB.swap

Change the permission:

sudo chmod 600 /mnt/1GiB.swap

Create a swap:

sudo mkswap /mnt/1GiB.swap


sudo swapon /mnt/1GiB.swap

Verify swap file exists:

cat /proc/swaps

To make the swap file available on boot:

echo '/mnt/1GiB.swap swap swap defaults 0 0' | sudo tee -a /etc/fstab


Access to /tmp folder:

cd /tmp

Download the latest version of Kasm Workspaces to /tmp folder:

curl -O

Extract the package:

tar -xf kasm_release*.tar.gz

Run the installation script:

sudo bash kasm_release/

Accept the user agreement.

Wait for the installation to complete and this took a while.

Once it is complete, keep the information login detail safe.

Run the Application

Open the browser and type in https://{Public_IP_Address}

Kasm Login Page

Log in as admin.

Kasm Admin

To launch the app container, click the Workspaces tab.

Kasm Workspaces

Select Chrome for instance.

Kasm Launch Chrome

Click the Launch Session button.

This will launch a Chrome browser inside the browser.

Note: On the left-hand side, there is menu option.

Click the left-hand side menu icon:

That is it. This container running on the web is really cool. You can even run a full-blown Ubuntu desktop or Kali Linux or play Doom on the go!
