Comment 23 for bug 1708245

I noticed the addition of a new build-dependency, so I had a closer look and the shim 13 package ftbfs on trusty:

The expectation is that the package is buildable from source in each release that we publish it to, even though in practice we are unlikely to do this for any but the devel series.

Is there a missing update to gnu-efi?
