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 the refs are the newest available. 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.

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.
