# flatpak-create-usb

## 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.
