Ubuntu 18.04.2 LTS was delayed due to boot error

Canonical announced today that the upcoming Ubuntu 18.04.2 LTS (Bionic Beaver) operating system will be delayed by one week, and the latest time will be pushed back to February 14, due to startup errors that cannot be fixed in time. In a mailing list announcement released earlier today, Canonical’s Adam Conrad announced that Ubuntu 18.04.2 LTS will be released on Valentine’s Day on February 14 next week instead of starting on February 7. The reason for the delay seems to be the critical boot error in Linux 4.18 kernel.

Due to LP: #1814555, we're delaying the point release by a week to get
a new kernel tested and pushed through the pipe.

Don't take this as an invitation to try to get all your pet bugs fixed
in the next few days, but if you've seen anything else in your testing
that would be critical to fix for boot/install, please esalate it NOW,
so we can address those in the same iteration and make sure 18.04.2 is
as shiny as can be.

Also, don't let this discourage you from testing things today, so bugs
can be fixed before next week.  Only a select few packages will change
over the next few days, so this is a good approximation of the final.

Ubuntu 18.04.2 LTS also introduces a new installation medium for users who want to deploy Ubuntu 18.04 LTS (Bionic Beaver) operating system on new computers without having to download hundreds of updates after installation. Existing Ubuntu 18.04.1 LTS users only need to select an update to run Ubuntu 18.04.2 LTS.
