Canonical apologizes for not launching on Ubuntu 18.10 & 18.04

Canonical apologizes for boot failure on Ubuntu 18.10 & 18.04, and now has a fix for it.


Η Canonical released a new kernel update for Ubuntu 18.10 (Cosmic Cuttlefish) and Ubuntu 18.04.1 LTS (Bionic Beaver) to address the boot failure created by the latest kernel security code.

The problematic version of kernel security released by Canonical on February 4 was available for Ubuntu 18.10, Ubuntu 16.0.4 LTS, and Ubuntu 14.04 LTS, but only Ubuntu 18.10 engines were affected by the error that could prevent boot if the machine was using some graphics chipsets.

Specifically Canonical said : “USN-3878-1 has identified vulnerabilities in the Linux kernel. Unfortunately, this update introduced a problem that could prevent systems from starting with specific graphics chipsets. This update fixes the problem. We apologize for the inconvenience. "

The problem affects not only the Ubuntu 18.10 (Cosmic Cuttlefish) systems, but also the Ubuntu 18.04 LTS (Bionic Beaver) running the Linux 4.18 HWE (Hardware Enablement) kernel.
