An updated version of Ubuntu 20.04.2 LTS has been released to address a regression with the installer.

Ubuntu 20.04.2.0 hotfix released

Shortly after the release of Ubuntu 20.04.2, on Thursday February 4 2021, a regression was discovered[1] which means that on certain systems and under certain specific conditions the Ubuntu installer can fail to install a Linux kernel. This renders the system unable to boot.

After carefully analysing the impact of this regression, the release team took the decision to reissue images of 20.04.2 with a corrected version of the installer[2]. These images are now available, versioned as 20.04.2.0. Only the Ubuntu flavours listed below are affected. If you have downloaded the 20.04.2 release of any of these flavours, we encourage you to re-download the updated versions.

Kubuntu
Ubuntu Budgie
Ubuntu Desktop
Ubuntu Kylin
Ubuntu MATE
Ubuntu Studio
Xubuntu
