Hello, I'm trying to build a custom bluebuild image from source (ghcr.io/ublue-os/base-main as a base image, if that's relevant), but it fails on the last step, saying it can't find the actual image

× Failed to create ISO

I'm not quite sure how this could be happening, it's worth mentioning that the github action works perfectly this is the exact build command I used (I also tried with normal /tmp) sudo ~/.cargo/bin/bluebuild generate-iso --iso-name weird-os.iso --tempdir build recipe recipes/recipe.yml

Have you tried running it without specifying a tempdir? Alternatively, you could build the iso from the existing image rather than the recipe.

Using a tempdir or not doesn't change anything, but I supposed building from an image does work
