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.
