[Bug 707392] Re: Not possible to upgrade untrusted packages

[rduke15]

Same problem in 12.04 LTS: cannot install updates from an unsigned
repository.

"apt-get upgrade" prompts, and lets the user decide whether to install
or not:

    WARNING: The following packages cannot be authenticated!
         unsigned-package1 package2 etc.
    Install these packages without verification [y/N]? y 

Update-manager should have a similar behaviour:

- Either give the option to upgrade the package(s) without verifictaion

- Or upgrade the other (authenticated) packages, and tell the user that
the unauthenticated package(s) should be upgraded by running "apt-get
upgrade" at the command-line.

Title:
  Not possible to upgrade untrusted packages

Status in “update-manager” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: update-manager

  -------------------
  Summary: update-manager does not allow the download/installation of updated packages from "unauthenticated" sources.  Previous versions of update-manager have always given an option to continue anyway.
  -------------------

  As part of my list of updates this morning I had one from a third
  party (Squeezebox Server from debian.slimdevices.com), which is not
  key-signed.

  When I selected OK to upgrade all of them, I got a message box
  "Requires installation of untrusted packages" (The action would
  require the installation of packages from unauthenticated sources.).
  The only option is 'Close' and there is no indication of what to do to
  authorise this! It prevented me upgrading the other packages too,
  until I'd unchecked the squeezeboxserver package.

  I guess I'll have to do it via apt-get.

  I'm running 10.10, fully up-to-date, and update-manager version 1:0.142.20.
