 Take my temporary fork of Mobian Recipes instead, for now: https://salsa.debian.org/erebion/mobian-recipes/-/tree/erebion/sargo-build?ref_type=heads
 
+Make sure you check out my branch `sargo-build` which includes a couple of workarounds for changes which are not yet in the repos, but will be soon.

 The fork will be maintained until there are official Mobian images for the Pixel 3a.

 (If you replace `mobian` with your own username, you will have to use that one for SSH later, of course)
 
 Wait. It takes a while.
