For GOS 21.04, a new patch level is available:
This release fixes an error where the upgrade from GOS 21.04 to GOS 22.04 failed when the SSH login protection feature was enabled. To prevent the error, the SSH login protection is now disabled automatically during the upgrade to GOS 22.04, and automatically re-enabled after the upgrade is finished.
Please note: GOS 21.04 will reach its end-of-life soon and will be retired end of March 2023. We strongly recommend everyone to upgrade to GOS 22.04.
For assistance in upgrading to a supported version, please contact the Greenbone Enterprise Support.
In total, GOS 21.04.25 covers 1 improvement and 2 bug fixes. For a complete list of changes, see the Roadmap & Lifecycle page:
