[Bug 2086623] Re: apt-get install does not downgrade packages with -t

[Jarno Suni]

Well, -t doesn't work, if I want to downgrade packages after disabling a
PPA repository. I have to add <package/target-release> for each argument
separately. I think the system should support easy downgrade when some
PPAs are removed.

Title:
  apt-get install does not downgrade packages with -t

Status in apt package in Ubuntu:
  Opinion

Bug description:
  Suppose package x has greater version than the latest one in
  repositories.

  sudo apt-get install -t=$(lsb_release -cs) x

  does not downgrade the package, but

  sudo apt-get install x/$(lsb_release -cs)

  does.

  I don't see why it shouldn't downgrade by the first command, too.

  Besides, I request an option to retain package's auto/manual state in
  this operation.
