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.
