Installing Old Versions

Occasionally, using older versions of Kurtosis is necessary. For example, when working with a Starlark Kurtosis package that was initially developed with an older version of Kurtosis, we might want rollback our Kurtosis version to ensure the version of Kurtosis we are running is compatible with the Kurtosis package.

The instructions in this guide will walk you through installing and using an older version of Kurtosis. To see what versions are available, reference our changelog.

If you're looking to install the latest version of Kurtosis, see here.

brew (MacOS)

1. Uninstall your current version of Kurtosis

   brew uninstall kurtosis-tech/tap/kurtosis-cli
2. Install an earlier version of Kurtosis (eg. 0.68.6)

   brew install kurtosis-tech/tap/kurtosis-cli@<version>

apt (Ubuntu)

caution

If you already have kurtosis-cli package installed, we recommend uninstalling it first using:

sudo apt remove kurtosis-cli

echo "deb [trusted=yes] https://apt.fury.io/kurtosis-tech/ /" | sudo tee /etc/apt/sources.list.d/kurtosis.list
sudo apt update
sudo apt remove kurtosis-cli
sudo apt install kurtosis-cli=<version> -V

yum (RHEL)

caution

If you already have kurtosis-cli package installed, we recommend uninstalling it first using:

sudo yum remove kurtosis-cli

echo '[kurtosis]
name=Kurtosis
baseurl=https://yum.fury.io/kurtosis-tech/
enabled=1
gpgcheck=0' | sudo tee /etc/yum.repos.d/kurtosis.repo
sudo yum remove kurtosis-cli
sudo yum install kurtosis-cli-<version>

deb, rpm, and apk

Download the appropriate artifact from the release artifacts page.

Windows

The Kurtosis CLI cannot be installed directly on Windows. Windows users are encouraged to use Windows Subsystem for Linux (WSL) to use Kurtosis.

tip

In order to upgrade Kurtosis to another version after you've performed a downgrade (i.e. installed a historical version), you must first uninstall the version of Kurtosis you've installed and re-install Kurtosis. When using Homebrew, the workflow will be (replacing HISTORICAL-VERSION with the historical version you have installed):

1. brew uninstall brew uninstall kurtosis-tech/tap/kurtosis-cli@HISTORICAL-VERSION
2. brew install kurtosis-tech/tap/kurtosis-cli for upgrading to the latest version or brew install kurtosis-tech/tap/kurtosis-cli@TARGET-VERSION for upgrading to a specific version
3. kurtosis engine restart
