Canonical has re-released the Ubuntu 20.04.2 LTS desktop images today due to an installation bug that could render OEM installations unbootable. A couple of days ago, the company behind the popular Ubuntu Linux distribution informed users on Twitter that the ISO images of the Desktop flavor of its recently released Ubuntu 20.04.2 LTS (Focal Fossa) are affected by a bug causing OEM installations via the Ubiquity installer to fail to boot due to missing kernel. As a reminder, Ubuntu 20.04.2 LTS comes with updated kernel and graphics stacks backported from the more recent Ubuntu 20.10 (Groovy Gorilla) operating system series. As such, this Focal Fossa point release is powered by the Linux 5.8 kernel and Mesa 20.3 graphics stack. According to the Launchpad entry of this bug, only certain machines were affected and it happened when networking was enabled, which means that if you did an offline installation everything worked fine. “Shortly after the release of Ubuntu 20.04.2, on Thursday February 4 2021, a regression was discovered 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,” said Canonical. This is another example why Canonical needs to revamp its Ubiquity installer on Ubuntu Desktop images.

Hi Rex.  Just want you to know that even though I can't be there in person, I still really appreciate all the work you guys do to educate the public on Linux. The group has really grown over the years, and I still read every update.  Sincerely, thank you!

This news has caused me to re-download the four of the six Ubuntu ISOs that use Ubiquity as the installer.  Better safe than sorry even though I checked each after the download and all six booted.  If any of you downloaded 20.04.2 for Ubuntu, Xubuntu, Ubuntu Budgie, or Ubuntu Mate, I would recommend that you re-download the ISO.  Since Kubuntu and Lubuntu use Calamares, they should not be affected.
