Hi,
Unfortunately, the patch does not seem to solve the problem. Running
Ubuntu 18.04 LTS with kernel 4.15.0-64, the crash still occurs with the
same signature :

Hi,
We are also affected by this bug.
Adding linux-meta in the loop because a simple solution could be to now
add a tighter dependency on the linux-image-4.4.0-*-generic package,
that means linux-base (>= 4.5ubuntu1~16.04.1).

Hi Eric,
I confirm that this behaviour can only be reproduced in 'uu' context and
only in 'shutdown mode'.
I can also confirm that the upgrade process is now OK in Bionic with
your test package :

@Eric : The server was installed with a 4.15.0-34.37 kernel from a

@Eric : Is cloud-init installed on your system. If not, can you install
it and try again please ? Indeed, as you can see in my first comment,
removing the cloud-init dependency on the linux-cloud-tools-common makes
the update process work well. So it seems to be related with cloud-init.

@Eric, no, it is not necessary. We encountered the same problem on AWS

Hi Eric,
The downgrade operation you saw is just because I've used the same
server to give you the logs and to test the step-by-step instructions
before writing them on this bug report.
I can confirm that the issue can be reproduced any time starting from
the 2 versions (Xenial : 4.4.0-135.161, B

Hi all,
I suspect that this fix is now preventing unattended-upgrades (in
shutdown down) to upgrade the package linux-cloud-tools-common.
The update process hangs during "Preparing to unpack". The server
restarts after the unattended-upgrades service timeout expires.

Hi,
Will this kernel update be integrated in the security pocket, as we are

If not, is it possible to have a list of URLs, in order to download all
