NAME
       flatpak-create-usb - Copy apps and/or runtimes onto removable media.

SYNOPSIS
       flatpak create-usb [OPTION...] MOUNT-PATH REF...

DESCRIPTION
       Copies the specified apps and/or runtimes REFs onto the removable media
       mounted at MOUNT-PATH, along with all the dependencies and metadata
       needed for installing them. This is one way of transferring flatpaks
       between computers that doesn't require an Internet connection. After
       using this command, the USB drive can be connected to another computer
       which already has the relevant remote(s) configured, and Flatpak will
       install or update from the drive offline (see below). If online, the
       drive will be used as a cache, meaning some objects will be pulled from
       it and others from the Internet. For this process to work a collection
       ID must be configured on the relevant remotes on both the source and
       destination computers, and on the remote server.

       On the destination computer one can install from the USB (or any
       mounted filesystem) using the --sideload-repo option with flatpak
       install. It's also possible to configure sideload paths using symlinks;
       see flatpak(1). Flatpak also includes systemd units to automatically
       sideload from hot-plugged USB drives, but these may or may not be
       enabled depending on your Linux distribution.

       Each REF argument is a full or partial identifier in the flatpak ref
       format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements
       except ID are optional and can be left out, including the slashes, so
       most of the time you need only specify ID. Any part left out will be
       matched against what is installed, and if there are multiple matches an
       error message will list the alternatives.

       By default this looks for both installed apps and runtimes with the
       given REF, but you can limit this by using the --app or --runtime
       option.

       All REFs must be in the same installation (user, system, or other).
       Otherwise it's ambiguous which repository metadata refs to put on the
       USB drive.

       By default flatpak create-usb uses .ostree/repo as the destination
       directory under MOUNT-PATH but if you specify another location using
       --destination-repo a symbolic link will be created for you in
       .ostree/repos.d. This ensures that either way the repository will be
       found by flatpak (and other consumers of libostree) for install/update
       operations.

       Unless overridden with the --system, --user, or --installation options,
       this command searches both the system-wide installation and the
       per-user one for REF and errors out if it exists in more than one.

OPTIONS
       The following options are understood:

       -h, --help
           Show help options and exit.

       -u, --user
           Copy refs from the per-user installation.

       --system
           Copy refs from the default system-wide installation.

       --installation=NAME
           Copy refs from a system-wide installation specified by NAME among
           those defined in /etc/flatpak/installations.d/. Using
           --installation=default is equivalent to using --system.

       --app
           Assume that all REFs are apps if not explicitly specified.

       --runtime
           Assume that all REFs are runtimes if not explicitly specified.

       --destination-repo=DEST
           Create the repository in DEST under MOUNT-PATH, rather than the
           default location.

       --allow-partial
           Don't print a warning when exporting partially installed commits,
           for example locale extensions without all languages. These can
           cause problems when installing them, for example if the language
           config is different on the installing side.

       -v, --verbose
           Print debug information during command processing.

       --ostree-verbose
           Print OSTree debug information during command processing.
