The download subcommand will download an image matching your system's architecture:
imgchroot download <distro> <release>
Currently the command only supports
ubuntu as a valid distro.
The download can resume an previous attempt if it was cancelled or connection is lost. Download will not re-download an image if it already exists.
Below is example output:
$ imgchroot download ubuntu bionic downloading https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img 346 of 346 MB (100.0%) @ 9.2 MB/sec image saved as bionic-server-cloudimg-amd64.img
