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 version.
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 detected vulnerabilities points in the Linux kernel. Unfortunately, this update introduced an issue that could prevent systems with certain graphics chipsets from booting. This update fixes the problem. We apologize for the inconvenience."
Users are asked to update their kernels immediately
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.
If useste Ubuntu 18.10 or Ubuntu 18.04 LTS with Linux kernel 4.18, please update your kernel immediately, with linux-image 4.18.0-15.16 for Ubuntu 18.10 or with linux-image 4.18.0-15.16 ~ 18.04 . 1 for Ubuntu 18.04 LTS.
