The following options are understood:
-h, --help
Show help options and exit.
-u, --user
Update a per-user installation.
--system
Update the default system-wide installation.
--installation=NAME
Updates a system-wide installation specified by NAME
among those defined in /etc/flatpak/installations.d/. Using
--installation=default is equivalent to using --system.
--share=SUBSYSTEM
Share a subsystem with the host session. This overrides
the Context section from the application metadata. SUBSYSTEM must be one of:
network, ipc. This option can be used multiple times.
--unshare=SUBSYSTEM
Don't share a subsystem with the host session. This
overrides the Context section from the application metadata. SUBSYSTEM must be
one of: network, ipc. This option can be used multiple times.
--socket=SOCKET
Expose a well-known socket to the application. This
overrides to the Context section from the application metadata. SOCKET must be
one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus,
ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be
used multiple times.
--nosocket=SOCKET
Don't expose a well-known socket to the application. This
overrides to the Context section from the application metadata. SOCKET must be
one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus,
ssh-auth, pcsc, cups, gpg-agent, inherit-wayland-socket. This option can be
used multiple times.
--device=DEVICE
Expose a device to the application. This overrides to the
Context section from the application metadata. DEVICE must be one of: dri,
input, kvm, shm, all. This option can be used multiple times.
--nodevice=DEVICE
Don't expose a device to the application. This overrides
to the Context section from the application metadata. DEVICE must be one of:
dri, input, kvm, shm, all. This option can be used multiple times.
--allow=FEATURE
Allow access to a specific feature. This updates the
[Context] group in the metadata. FEATURE must be one of: devel, multiarch,
bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.
See flatpak-build-finish(1) for the meaning of the various
features.
--disallow=FEATURE
Disallow access to a specific feature. This updates the
[Context] group in the metadata. FEATURE must be one of: devel, multiarch,
bluetooth, canbus, per-app-dev-shm. This option can be used multiple
times.
--filesystem=FILESYSTEM
Allow the application access to a subset of the
filesystem. This overrides to the Context section from the application
metadata. FILESYSTEM can be one of: home, host, host-os, host-etc,
xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures,
xdg-public-share, xdg-templates, xdg-videos, xdg-run, xdg-config, xdg-cache,
xdg-data, an absolute path, or a homedir-relative path like ~/dir or paths
relative to the xdg dirs, like xdg-download/subdir. The optional :ro suffix
indicates that the location will be read-only. The optional :create suffix
indicates that the location will be read-write and created if it doesn't
exist. This option can be used multiple times. See the "[Context]
filesystems" list in flatpak-metadata(5) for details of the
meanings of these filesystems.
--nofilesystem=FILESYSTEM
Undo the effect of a previous
--filesystem=FILESYSTEM in the app's manifest or a lower-precedence
layer of overrides, and/or remove a previous
--filesystem=FILESYSTEM
from this layer of overrides. This overrides the Context section of the
application metadata. FILESYSTEM can take the same values as for
--filesystem, but the :ro and :create suffixes are not used here. This
option can be used multiple times.
This option does not prevent access to a more narrowly-scoped
--filesystem. For example, if an application has the equivalent of
--filesystem=xdg-config/MyApp in its manifest or as a system-wide
override, and flatpak override --user --nofilesystem=home as a per-user
override, then it will be prevented from accessing most of the home
directory, but it will still be allowed to access
$XDG_CONFIG_HOME/MyApp.
As a special case, --nofilesystem=host:reset will ignore
all --filesystem permissions inherited from the app manifest or a
lower-precedence layer of overrides, in addition to having the behaviour of
--nofilesystem=host.
--add-policy=SUBSYSTEM.KEY=VALUE
Add generic policy option. For example,
"--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2" would
map to this metadata:
[Policy subsystem]
key=v1;v2;
This option can be used multiple times.
--remove-policy=SUBSYSTEM.KEY=VALUE
Remove generic policy option. This option can be used
multiple times.
--env=VAR=VALUE
Set an environment variable in the application. This
overrides to the Context section from the application metadata. This option
can be used multiple times.
--unset-env=VAR
Unset an environment variable in the application. This
overrides the unset-environment entry in the [Context] group of the metadata,
and the [Environment] group. This option can be used multiple times.
--env-fd=FD
Read environment variables from the file descriptor
FD, and set them as if via
--env. This can be used to avoid
environment variables and their values becoming visible to other users.
Each environment variable is in the form VAR=VALUE
followed by a zero byte. This is the same format used by env -0 and
/proc/*/environ.
--own-name=NAME
Allow the application to own the well-known name NAME on
the session bus. This overrides to the Context section from the application
metadata. This option can be used multiple times.
--talk-name=NAME
Allow the application to talk to the well-known name NAME
on the session bus. This overrides to the Context section from the application
metadata. This option can be used multiple times.
--no-talk-name=NAME
Don't allow the application to talk to the well-known
name NAME on the session bus. This overrides to the Context section from the
application metadata. This option can be used multiple times.
--system-own-name=NAME
Allow the application to own the well known name NAME on
the system bus. If NAME ends with .*, it allows the application to own all
matching names. This overrides to the Context section from the application
metadata. This option can be used multiple times.
--system-talk-name=NAME
Allow the application to talk to the well known name NAME
on the system bus. If NAME ends with .*, it allows the application to talk to
all matching names. This overrides to the Context section from the application
metadata. This option can be used multiple times.
--system-no-talk-name=NAME
Don't allow the application to talk to the well known
name NAME on the system bus. If NAME ends with .*, it allows the application
to talk to all matching names. This overrides to the Context section from the
application metadata. This option can be used multiple times.
--persist=FILENAME
If the application doesn't have access to the real
homedir, make the (homedir-relative) path FILENAME a bind mount to the
corresponding path in the per-application directory, allowing that location to
be used for persistent data. This overrides to the Context section from the
application metadata. This option can be used multiple times.
--reset
Remove overrides. If an APP is given, remove the
overrides for that application, otherwise remove the global overrides.
--show
Shows overrides. If an APP is given, shows the overrides
for that application, otherwise shows the global overrides.
-v, --verbose
Print debug information during command processing.
--ostree-verbose
Print OSTree debug information during command
processing.
