flatpak-create-usb - Copy apps and/or runtimes onto removable media.
flatpak create-usb [OPTION...] MOUNT-PATH REF...
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
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
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.
The following options are understood:
Show help options and exit.
Copy refs from the per-user installation.
Copy refs from the default system-wide
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.
Assume that all REFs are apps if not explicitly
Assume that all REFs are runtimes if not explicitly
Create the repository in DEST under MOUNT-PATH, rather
than the default location.
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.
Print debug information during command processing.
