<title>Description</title>
<para>
Updates applications and runtimes. <arg choice="plain">REF</arg> is a reference to the
application or runtime to update. If no <arg choice="plain">REF</arg> is given, everything
is updated, as well as appstream info for all remotes.
</para>
<para>
Each <arg choice="plain">REF</arg> argument is a full or partial indentifier 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.
</para>
<para>
By default this looks for both apps and runtimes with the given <arg choice="plain">REF</arg>,
but you can limit this by using the --app or --runtime option, or by supplying the initial
element in the REF.
</para>
<para>
Normally, this command updates the application to the tip
of its branch. But it is possible to check out another commit,
with the --commit option.
</para>
<para>
If the configured remote for a ref being updated has a collection ID configured on it,
flatpak will search mounted filesystems such as USB drives as well as Avahi services
advertised on the local network for the needed refs, in order to support
offline updates. See <citerefentry><refentrytitle>ostree-find-remotes</refentrytitle><manvolnum>1</manvolnum></citerefentry>
for more information.
</para>
<para>
Note that updating a runtime is different from installing
a different branch, and runtime updates are expected to keep
strict compatibility. If an application update does cause
a problem, it is possible to go back to the previous
version, with the --commit option.
</para>
<para>
Unless overridden with the --user, --system or --installation option, this command updates
any matching refs in the standard system-wide installation and the per-user one.
