> In case the package list should be grabbed or the system should be
> upgraded, pakfire got called which writes a lock file to prevent from

> In case update or upgrade has been performed via WUI, pakfire has been called
> and written the file in the background but the WUI script has been
> executed further and because of a race condition it did not recognize
> the lockfile at this moment because it was not present.
> 
> So a simple sleep should to the trick and give pakfire the required time
> to write out it's lockfile.

> Fixes #12696.
