acroread packages obsoleted

[T o n g <mlist4suntong@yahoo.com>]

Hi,

The last time I did aptitude update, I found my acroread packages (from 
debian-multimedia) are now obsolete, which contain,

 acroread, acroread-data, acroread-escript and acroread-plugins

 $ apt-cache policy acroread
 acroread:
  Installed: 9.1.0-0.4
  Candidate: 9.1.0-0.4
  Version table:
  *** 9.1.0-0.4 0
        100 /var/lib/dpkg/status

How can I have acroread now?

Thanks
