[Bug 107221] Re: apt-get should allow downgrade also

[Jarno Suni]

I think it would be good, if apt could downgrade the dependencies, too.
I reported a related bug #1857018.

Title:
  apt-get should allow downgrade also

Status in apt package in Ubuntu:
  Fix Released

Bug description:
  Recently after installing KDE 3.5.6 on Kubuntu with apt-get dist-
  upgrade I have been facing some problems. I would like to downgrade my
  KDE back to 3.5.5. But apt-get does not provide any way of doing this.
  Please provide a downgrade command for apt-get so that I am asked
  which version I want to downgrade to, providing the next available
  lower version as default (so I can just keep hitting Enter through the
  downgrade process). The session would look something like this:

  $ sudo apt-get downgrade kdelibs4c2a
  Password:
  The current installed version of kdelibs4c2a is: 4:3.5.6-0ubuntu1~edgy1.
  The next lower available version of kdelibs4c2a is: 4:3.5.5-0ubuntu3.4 from http://security.ubuntu.com edgy-security/main
  Would you like to downgrade? [y/N] y
  This downgrade would break the dependencies of the following packages:
  kate kdesktop ... kwin [blah blah blah]
  Would you like to downgrade them also? [y/N] y
