MakeAppx : error : 0x80080215

[apple-ouyang]

I can deploy the solution, and my ditro runs well in my computer.
When I want to publish it, I have done those steps:

1. I register a company account.
2. I have filled the info in MyDitro.appxmanifest, and change the "mydistro" to "openEuler".
3. I right click the "DistroLauncher-Appx" in the solution window, then "publiss", then "Create App packages ..."
4. I finish filling info, then click "create", then a lot of errors and warning show up:
   Here is my full build output:
   Hoping someone can help me.
   Many thanks to you !

I get the same error when trying to build my custom Ubuntu 20.04 distro using the build.bat.

I solved the problem, but I did't remember what have I done. Sorry it was long time ago for me. Here is the repo I am using now, I changed a lot of placeses to get it work. Hope it will help you.

I think i figured out the issue. I searched the error message and came across a forum post describing a solution. I said I needed to set the <TargetDeviceFamily> to something greater than 10.0.17xxx. Retargeting the solution to use 10.0.19041 seemed to fix the error. Thanks, though!
