[Bug 512190] Re: "apt-get --ignore-missing install" fails when it can't find a package

[Christian Hudon]

Actually, aptitude is not a great fit for that kind of usage, as it will
also happily start automatically uninstalling a bunch of packages that
are "not needed" anymore (not available upstream). And there's no way to
prevent it from doing that. It also searches in the package description,
etc. instead of just the package name, which is much slower when one
have a long list of packages to install or remove.

Title:
  "apt-get --ignore-missing install" fails when it can't find a package

Status in “apt” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: apt

  I have a script for configuring Ubuntu after installation.  I'd like
  to be able to run one apt-get command to download and install all the
  packages I normally use.  Unfortunately, the availability of a package
  varies over time and release.  Upon reviewing the manpages, it appears
  that "--ignore-missing" should do what I want, but it still causes
  apt-get to fail:

  sudo apt-get --ignore-missing install kdvi; echo $?
  Reading package lists... Done
  Building dependency tree
  Reading state information... Done
  E: Couldn't find package kdvi
  100

  Now, I could loop and run "apt-get install" for every package,
  ignoring the exit codes, but that doesn't seem to be the way apt-get
  is supposed to be used.

  If --ignore-missing does something other than what I want, the manual
  pages need to make clear exactly what it does.  Furthermore it seems
  reasonable to request an option to allow apt-get to proceed even if it
  doesn't find all the requested packages - failing to install ANY of
  the specified packages when one isn't present seems to be the wrong
  behavior in this context.
