Title:
  ttf-mscorefonts-installer drop-priv warnings and download errors
  during install

Status in msttcorefonts package in Ubuntu:
  Confirmed

Bug description:
  for several days now, updates that involve updating or re-configuring
  ttf-mscorefonts-installer have thrown warnings.  After looking at my
  apt logs, there appears to be a couple issues.

  First is a warning about not being able to drop privileges... which
  admittedly may be a red herring:

  W: Can't drop privileges for downloading as file '/var/lib/update-notifier/package-
  data-downloads/partial/andale32.exe' couldn't be accessed by user '_apt'. - pkgAcqu
  ire::Run (13: Permission denied)

  Next is a failure to download arial32 from sourceforge which results
  in a full error due to a 400 Return Code:

  
  ttf-mscorefonts-installer: downloading http://downloads.sourceforge.net/corefonts/arial32.exe

      W: Can't drop privileges for downloading as file '/var/lib/update-notifier/package-data-downloads/partial/arial32.exe' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)
      E: Failed to fetch https://svwh.dl.sourceforge.net/project/corefonts/the fonts/final/arial32.exe  400  Bad request
      E: Download Failed

  This goes on and completes, however, the warnings always trigger
  annoying popups that could be confusing for users who don't understand
  what's going on (or just annoying for those of us who have to close
  the stinking pop-up box ever time updates are applied (which could be
  daily depending on how users have update manager configured).

  To reporoduce this, I simply did a re-install of ttf-mscorefonts-
  installer and was able to easily reproduce the warnings and errors:

  bladernr at galactica:/var/log/apt$ sudo apt-get install --reinstall ttf-mscorefonts-installer

  This appears to be an upstream issue, however, the drop-privileges
  issue is bothersome as well.
