Question: I'm currently using the Qt Installer Framework and managed to set up an online repository. What I want to know is:

Does the Framework provide some kind of "auto-update" mechanism, e.g. a plugin/service that checks for updates every time the program/system starts?  

Check for updates would be enough, since the installation itself can be done using the maintanance tool.

All I could find about this topic was this small sentence:

> 
> End users can use the maintenance tool to install additional components from the server after the initial installation, as well as to **receive automatic updates** to content as soon as the updates are published on the server. 
>

from here: <http://doc.qt.io/qtinstallerframework/ifw-overview.html#choosing-installer-type>

Thanks for your help!

**Edit:** Suggestion

Answer: 
In the latest Qt Installer Framework 4.1 `--checkupdates` returns nothing, use `ch` or `check-updates` instead.

```
Commands:
  in, install - install default or selected packages - <pkg ...>
  ch, check-updates - show available updates information on maintenance tool
  up, update - update all or selected packages - <pkg ...>
  rm, remove - uninstall packages and their child components - <pkg ...>
  li, list - list currently installed packages - <regexp>
  se, search - search available packages - <regexp>
  co, create-offline - create offline installer from selected packages - <pkg ...>
  pr, purge - uninstall all packages and remove entire program directory

```
There's a section in the guide about how to do it, but they call it promoting updates rather than auto updates, [IFW Updates on doc.qt.io](http://doc.qt.io/qtinstallerframework/ifw-updates.html).
