  • Can I use snapcraft with LXD on macOS? - answered by bard

    No, directly using Snapcraft with LXD on macOS isn't possible. Here's the breakdown:
    
    LXD limitations: macOS itself doesn't have built-in LXD support. LXD relies on functionalities offered by the Linux kernel, which macOS lacks.
    
    Snapcraft on macOS: While Snapcraft itself can run on macOS, it's limited to store-related operations. It cannot build snaps directly due to the missing Linux environment.
    
    There are alternative approaches to consider:
    
    Remote LXD instance: You can point Snapcraft to a remote LXD instance running on a Linux machine. This allows leveraging LXD for building while using your macOS machine for development. Tools like "cleanbuild" can facilitate this setup.
    
    Multipass: Snapcraft defaults to using Multipass (a lightweight Ubuntu virtualization solution) on macOS for building snaps. This provides a Linux environment for the build process within macOS.
    
    If you're comfortable with virtualization, using Multipass might be a simpler solution for building snaps on your macOS machine.
    

    Here are some alternative approaches:
    
    Build with LXD: If you're on Raspberry Pi itself, consider using LXD for building snaps. This ensures the snap targets the Raspberry Pi's architecture from the get-go.
    
    Multipass workaround (advanced): There are complex workarounds involving creating a custom cloud image for Multipass that matches Raspberry Pi's architecture. This approach is not recommended for beginners due to its involved nature. You can search for "Multipass Raspberry Pi cloud image" for more information if you're interested.
    
    For most scenarios, building with LXD directly on your Raspberry Pi is the recommended approach for ensuring compatibility with the target platform.
