We’re pleased to announce the stable release of Qubes OS 4.3.2! This patch release aims to consolidate all the security updates and bug fixes that have occurred since the previous stable release. Our goal is to provide a secure and convenient way for users to install (or reinstall) the latest stable Qubes release with an up-to-date ISO. The ISO and associated verification files (https://doc.qubes-os.org/en/latest/project-security/verifying-signatures.html) are available on the downloads (https://www.qubes-os.org/downloads/) page.

How to get Qubes 4.3.2



If you’d like to install Qubes for the first time or perform a clean reinstallation on an existing system, there’s never been a better time to do so! Simply download (https://www.qubes-os.org/downloads/) the Qubes 4.3.2 ISO and follow our installation guide (https://doc.qubes-os.org/en/r4.3/user/downloading-installing-upgrading/installation-guide.html).


If you’re currently on Qubes 4.3 (including 4.3.0, 4.3.1, and 4.3.2-rc1), update normally (https://doc.qubes-os.org/en/r4.3/user/how-to-guides/how-to-update.html) (which includes upgrading any EOL templates and standalones (https://doc.qubes-os.org/en/r4.3/user/how-to-guides/how-to-update.html#upgrading-to-avoid-eol) you might have) in order to make your system essentially equivalent to the stable Qubes 4.3.2 release. No reinstallation or other special action is required.


If you’re still using Qubes 4.2, you should upgrade from 4.2 to 4.3 (https://doc.qubes-os.org/en/r4.2/user/downloading-installing-upgrading/upgrade/4_3.html) immediately, since Qubes 4.2 has already reached end of life (EOL) (https://www.qubes-os.org/news/2026/06/21/qubes-os-4-2-has-reached-end-of-life/).



In all cases, we strongly recommend making a full backup (https://doc.qubes-os.org/en/latest/user/how-to-guides/how-to-back-up-restore-and-migrate.html) beforehand.

Known issues in Qubes 4.3.2

It’s possible that templates restored in 4.3.2 from a pre-4.3 backup may continue to target their original Qubes OS release repos (#8701 (https://github.com/QubesOS/qubes-issues/issues/8701)). After restoring such templates in 4.3.2, enter the following additional commands in a dom0 terminal:

sudo qubes-dom0-update -y qubes-dist-upgrade
sudo qubes-dist-upgrade --releasever=4.3 --template-standalone-upgrade -y


This will automatically choose the templates that need to be upgraded. The templates will be shut down during this process.
