Canonical has been released from scratch its ISO Ubuntu 20.04.2 LTS today due to an installation error that could make the OEM installation non-bootable.
A few days ago, the company informed them users στο Twitter ότι τα ISO του Ubuntu 20.04.2 LTS (Focal Fossa) που κυκλοφόρησαν recently are affected by a bug that causes new OEM installations through Ubiquity to fail to boot.
Kernel is responsible for the problem. The functional Ubuntu 20.04.2 LTS comes with updated kernels and graphics stacks supported by the latest Ubuntu 20.10 (Groovy Gorilla) series.
So, this point release of the Focal Fossa version runs with the Linux 5.8 kernel and the Mesa 20.3 graphics stack.
According to error registration in Launchpad, only certain machines are affected and it happens when networking was enabled, which means that if you did an offline installation, everything will be fine.
"Shortly after the release of Ubuntu 20.04.2, on Thursday, February 4, 2021, an error was discovered which means that on some systems and under certain conditions, the Ubuntu installer may fail to install a Linux kernel. "This makes the system impossible to start," says Canonical.
This is another example of why Canonical needs to upgrade the Ubiquity installer to Ubuntu Desktop ISO.
For all of the above Canonical has released new ISO images for Ubuntu Desktop and for all official flavors (Xubuntu, Ubuntu MATE, Ubuntu Budgie, Ubuntu Studio and Ubuntu Kylin).
Lubuntu is not affected by these issues, as it uses Calamares as an installer.
Existing users are not affected by this issue.
