UWP appx package Signtool "Error: SignerSign() failed." (-2147024885/0x8007000b)

EDIT

Event log error was this:

    error 0x8007000B: The app manifest publisher name (CN=...) 
must match the subject name of the signing certificate 
(CN={19BE29DF-4812-4F2E-8FC1-A138B146946A}).

The command below now seems to work. So either user error on my part that I cannot identify or something hinky with the state of machine when I was seeing this. That guid associated with the signing cert in the event log message is not what the cert shows in the Certificate Manager snap-in, which is weird.

Original Question

I am attempting to sign a UWP appx package that was generated using MakeAppx.exe. The pfx is a developer code signing certificate generated with these commands from https://msdn.microsoft.com/windows/uwp/porting/desktop-to-uwp-manual-conversion.

C:\> MakeCert.exe -r -h 0 -n "CN=<publisher_name>" -eku 1.3.6.1.5.5.7.3.3 -pe -sv <my.pvk> <my.cer>
C:\> pvk2pfx.exe -pvk <my.pvk> -spc <my.cer> -pfx <my.pfx>

The private key is in my trusted root cert store and worked when I generated an appx from an installer using the Desktop App Converter.

The command line I am using is:

signtool.exe sign -f <path to my pfx file> -fd SHA256 -v .\FishTank.appx

but SignTool is erroring with this:

The following certificate was selected:
    Issued to: ...
    Issued by: ...
    Expires:   Sat Dec 31 18:59:59 2039
    SHA1 hash: ...

Done Adding Additional Store
Error information: "Error: SignerSign() failed." (-2147024885/0x8007000b)

The certificate publisher matches what is in the appmanifest.xml

Just like answered here (though for a different error code) - you have to make sure that the Publisher name (in the AppxManifest.xml file) is the same as the certificate's publisher.

For more information, see here (in the bottom "Remarks" section).
