Downgrade packages from CLI?
I'm trying to downgrade some packages from a BASH script (I'm rewriting lp:ppa-purge using aptdaemon).
Aptdcon doesn't support downgrading, so I tried using dbus-send, but I can't figure out how to format the request. I've tried doing some basic calls like updating cache, but every combination I tried returned an error. I've tried running update-manager and capturing the message with dbus-monitor, but I haven't captured any any UpdateCache calls in neither session nor system bus. An example command that downgrades several packages would be ideal, but how do I make at least basic calls with dbus-send?

For reference: http://
You can use the CommitPackages method to downgrade packages. Please consider that downgrades are not supported by Debian or Ubuntu. The install scripts only can convert to a later version.
aptdcon has got an option --downgrade that allows you to downgrade the system. There isn't any need to use dbus-send (which would not work very well at all)
aptdcon --downgrade=
Thanks Sebastian Heinlein, that solved my question.
I must have seen an outdated version of aptdcon manpage then. Thanks a lot!
For some totally mysterious reason aptdcon just prints usage when I run this:
$ aptdcon --downgrade=
I've tried any combination I cound invent, escape everything that's escapable, and it still prints usage. Any ideas?

You can just use apt-get install xterm=246 to downgrade packages in oneiric
Thanks Sebastian Heinlein, that solved my question.
