Nr r r r r �ims_hitA r zAcquireProgress.ims_hitc C r )a� Prompt the user to change the inserted removable media. The parameter 'media' decribes the name of the media type that should be changed, whereas the parameter 'drive' should be the identifying name of the drive whose media should be changed. This method should not return until the user has confirmed to the user interface that the media change is complete. It must return True if the user confirms the media change, or False to cancel it. Fr )r �media�driver r r � media_changeJ s z AcquireProgress.media_changec C r )a Periodically invoked while the Acquire process is underway. This method gets invoked while the Acquire progress given by the parameter 'owner' is underway. It should display information about the current state.

Can be used with apt_pkg.Cdrom to produce an utility like apt-cdrom. The attribute 'total_steps' defines the total number of steps and can be used in update() to display the current progress. r c C r )z�Ask for the name of the cdrom.

This functions runs install actions. The parameter 'obj' may either be a PackageManager object in which case its do_install() method is called or the path to a deb file. If the object is a PackageManager, the functions returns the result of calling its do_install() method. Otherwise, the function returns the exit status of dpkg.
