FLATPAK CREATE-USB(1) flatpak create-usb FLATPAK CREATE-USB(1)
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.
