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 and flatpak install will prefer to install from it rather than the
       Internet if (a) each ref comes from a configured remote whose GPG keyring will be used for verification
       and (b) the refs on the drive are at least as new as what's available elsewhere (e.g. the Internet if
       you're online). 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) the same way you
       would install from the Internet, e.g. with flatpak install flathub org.gnome.Builder or using a GUI.

       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.

       --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.

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

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