Install KOS Studio on Linux

KOS Studio gives you, the developer, the tools necessary to create, package, run, and debug your KOS applications. It is the primary KOS development tool. Learn more about KOS Studio at:  Introducing KOS Studio. 

Requirement

  • Ubuntu LTS releases ( Ubuntu 24, 25)
  • curl installation should be present on the system, which may be installed with:
$ sudo apt install curl
  • If not installed, the script will use sudo apt commands to install the libfuse2 package. It will prompt the user to confirm the package installation.
  • You must enable hardware virtualization on your computer.
  • Installation to a Virtual Machine may cause problems, particularly if your Host OS is not Linux.

Installation Location

KOS Studio is a gateway to privileged data, including your repositories and API keys. By installing at the user level, you guarantee that no one else on your computer has access to the software, and it allows us to keep your application up-to-date without administrator privileges. KOS Studio is installed at:

~/kosStudio

Installation Instructions

  • To install KOS Studio, execute the following command from your terminal.
bash -c "$(curl -fsSL https://sause2tcccknaprod0001.blob.core.windows.net/release/kos-studio-install-bootstrap)"
  • The above command will run a carefully crafted script to install KOS Studio at the designated location. The script may prompt the user to install dependent components before installation.
  • If not installed, the script will use sudo apt commands to install the libfuse2 package. It will prompt the user to confirm the package installation.
  • Before installing KOS Studio, the script will ask the user to confirm the installation before proceeding. The output will look like :
