After compiling mender-artifact from source for Linux and Windows, I noticed that I cannot validate a signed image using the Windows binary. From what I can tell this is related to the use of “archive/tar” and how paths are handled between operating systems.

Behavior in Windows  
get-wmiobject -class win32\_operatingsystem

SystemDirectory : C:\WINDOWS\system32  
Organization : $COMAPANY

PS C:\path\mender-artifact-windows.exe --version  
mender-artifact version 62d044b  
PS C:\path\mender-artifact-windows.exe validate -k .\pub.key .\signed.mender  
reader: error getting header Payload number: can not get Payload order from tar path

$ ./mender-artifact --version

$ ./mender-artifact validate -k /mnt/c/path/pub.key /mnt/c/path/signed.mender

Interesting. Currently the `mender-artifact` binary is only validated (tested) for macOS and linux. I don’t currently have the time, or a VM with windows available to look at this, but PR’s are always welcome 😉
