shim-signed: missing versioned dep on sbsigntool (>= 0.6-0ubuntu10.1) package shim-signed 1.33.1~16.04.4+15+1533136590.3beb971-0ubuntu1 failed to install/upgrade: sub-processo script post-installation instalado retornou estado de saída de erro 127

[Impact]
Upgrades with shim-signed when only partial upgrades are done.

[Test case]
1) Install new system, with no updates
2) Run 'sudo apt-get update'
3) Run 'sudo apt-get install shim-signed'
4) Verify that sbsigntool is also updated to the new version.

[Regression potential]
Minimal; this simply adds a prerequisite package version for running 'kmodsign' on systems when installing DKMS modules that need to be self-signed. If sbsigntool is already installed and at the right version, or if kmodsign is not required, this makes no difference on the system.

[Steve Langasek (vorlon)]

shim-signed uses kmodsign from the sbsigntool package. It declares a dependency on sbsigntool, but the dependency is unversioned, and kmodsign was first introduced in xenial in sbsigntool 0.6-0ubuntu10.1.

shim-signed needs a versioned dependency on sbsigntool.

[Steve Langasek (vorlon)]

The version number is different for trusty, but the dependency needs to be versioned there as well for the same reason.
