Bug#928486: shim-signed:amd64 cannot be installed alongside shim-signed:i386

[adrian15 <adrian15sgd@gmail.com>]

Package: shim-signed
Version: 1.30+15+1533136590.3beb971-5
Severity: normal

Dear Maintainer,


I want to be able to build a live cd that has both ia32 and x64 Secure
Boot UEFI support.
So I need both shim-signed:amd64 and shim-signed:i386 installed.

After adding and apt amd64 architecture to an i386 system if I run:

apt-get install shim-signed:amd64 shim-signed:i386

I get this output:

Some packages could not be installed. This may mean that you have


requested an impossible situation or if you are using the unstable


distribution that some required packages have not yet been created


or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 shim-signed : Conflicts: shim-signed:amd64 but
1.30+15+1533136590.3beb971-5 is to be installed
 shim-signed:amd64 : Depends: shim-helpers-amd64-signed:amd64 (>=
1+15+1533136590.3beb971+5) but it is not going to be installed
                     Depends: mokutil:amd64 but it is not going to be
installed
                     Conflicts: shim-signed but
1.30+15+1533136590.3beb971-5 is to be installed
E: Unable to correct problems, you have held broken packages.


I would like to be able to install both packages at the same time
because generated binaries do not collide between them.

It would seem those packages are lacking some multi-arch declaration on
the package metadata.

Other similar packages which probably have the proper multi-arch
declaratio might be grub-efi-amd64-bin and grub-efi-ia32-bin packages.

Thank you very much!
