Problems with upgrading packages in unstable

["Edward Guldemond" <edward.guldemond@gmail.com>]

When running unstable on my amd64 system, I am encountering problems
upgrading five packages.  The packages with the problems are docker,
libbonobo2-0, libgtk2.0-bin, libselinux1, and openntpd.  After
upgrading them, they stay in the list of packages to be upgraded. 
Forcing a purge on them and reinstalling does not help the problem. 
This behavior started after moving from the archive on
amd64.debian.net to the ftp.us.debian.org mirror.

Here is the output from two subsequent "aptitude upgrade" runs:

ed@anang:~$ sudo aptitude upgrade
Reading package lists... Done
Building dependency tree... Done
Reading extended state information
Initializing package states... Done
Reading task descriptions... Done
Building tag database... Done
The following packages will be upgraded:
  docker libbonobo2-0 libgtk2.0-bin libselinux1 openntpd
5 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0B/306kB of archives. After unpacking 0B will be used.
Do you want to continue? [Y/n/?] y
(snipped output)

Thanks for your help!
