Title:
  Aptitude 0.8.3 (yakkety) hangs indefinitely after package list update

Status in aptitude package in Ubuntu:
  Fix Released
Status in aptitude package in Debian:
  Fix Released

Bug description:
  Aptitude 0.8.3 (as available in Ubuntu 16.10 Yakkety Yak) hangs
  indefinitely after the package list is updated.  The "Loading cache"
  box appears in the middle of the screen, but nothing else happens: the
  standard package display does NOT come up.

  The interface is still responsive, however: pressing "q" will allow
  the user to quit aptitude.  Selecting "Cancel pending actions" from
  the Actions menu also brings back the package list, but I am not sure
  whether the package lists are updated in this case.

  Further debugging shows that this issue only comes up if an error
  occurs during package list download.  In particular, having the
  following lines in /etc/apt/sources.list is enough to trigger the bug:

  deb     http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu yakkety main
  deb-src http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu yakkety main
  deb     http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu yakkety main
  deb-src http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu yakkety main

  After pressing "u", the List Update tab shows:

  http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu yakkety Release [ERROR]
   404  Not Found
  http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu yakkety Release [ERROR]
   404  Not Found

  as well as a dialog box "Some files were not downloaded successfully."
  Pressing Continue then triggers the bug (package display does not come
  up, hanging in "Loading cache").

  Previous versions of aptitude (0.7.4, as per Ubuntu 16.04 Xenial
  Xerus) showed the 404 messages and a dialog box:

  ┌──────────────────────────────────────────────────────────────────────────────┐
  │W: The repository 'http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu xenial    ▒│
  │   Release' does not have a Release file.                                    ▒│
  │                                    [ Ok ]                                    │
  └──────────────────────────────────────────────────────────────────────────────┘

  Clicking Ok would then bring up the package display, with an
  additional dialog box:

  ┌──────────────────────────────────────────────────────────────────────────────┐
  │W: The repository 'http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu xenial    ▒│

  │W: Failed to fetch                                                           ▒│

  │E: Some index files failed to download. They have been ignored, or old ones  ▒│

  │                                    [ Ok ]                                    │
  └──────────────────────────────────────────────────────────────────────────────┘

  This is correct behaviour.  The new version's behaviour (hanging) is a
  bug.

  Thanks!
