It was available only as a feature flag that allowed users to enable a remote LXD instance to handle the build with local mounts. On the other hand, Snapcraft 2.42 removes support for remote persistent containers, which was in the experimental phase for some time now and never got to be ready for production use. To try it out, you'll have to run the '$ SNAPCRAFT_BUILD_ENVIRONMENT=multipass snapcraft cleanbuild' command in the terminal emulator. In Snapcraft 2.42, there's a new feature called multipass cleanbuild support, which might come in handy to users of snapcraft cleanbuild with multipass installed. Snapcraft 2.42 comes less than two weeks after version 2.41, which improved the mechanism for overriding lifecycle steps, passthrough property, error reporting, and updated the dotnet, nodejs, and python plugins, to add even more enhancements to the utility that helps application developers to package their apps as Snaps. Canonical released over the weekend version 2.42 of its Snapcraft command-line tool for creating Snap packages on the Ubuntu Linux operating system.
