Hello,
I don't know if I'm in the right place to ask my question, if not I apologize.
I'm trying to build a grapheneos for a Pixel 8a. I followed the tutorial (https://grapheneos.org/build) and everything is ok until the building stage (https://grapheneos.org/build#building).
When i run m vendorbootimage vendorkernelbootimage target-files-package i get a couple of errors, i tryed to search for solutions online but didnt find...

here is what i get
