Dear Maintainer,

   * What led up to the situation?

I was updating my system when this package update failed to install. It only failed on one of my systems.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I just did a standard upgrade, which was ineffective.

   * What was the outcome of this action?

I received the following error:

I would also note there is a typo in the word "against" instead being "agsinst".

   * What outcome did you expect instead?

I expected all updates to install properly.

Hi Amy,

That's not a Debian version of the shim-signed package, and we fixed
this issue in version 1.50 in Debian.

That version suggests you might be using a Proxmox system? If so, you
should be talking to them rather than Debian directly here. I've added
a CC to their support team here for you.

Checking, they also have a Proxmox version of 1.51 in
shim-signed_1.51+pmx1+16.1-2+pmx1_amd64.deb which will almost
definitely fix this problem for you.

Anyway, closing this Debian bug - it's not a Debian issue.
