[Bug 756317] Re: Captive portals may corrupt apt translation indices

[Julian Andres Klode]

I already wrote it: The check already exist. It is in
pkgAcqIndex::Done() in apt-pkg/acquire-item.cc, it is just disabled in
commit c5f661b715fbd86fcbca694c44bb8422f01db267 for some type of indices
(optional ones like translations). I do not know why.

This is not a denial of service. APT clearly informs you that your lists
are broken, you can delete them, and things start working again. Unless
you hit one of those stupid portals again.

This bug is not for discussing thing. We know that the bug exists, but
we cannot fix this immediately.

We know that we need to enable the check again, but we first need to
figure out why we disabled it in the first place.

Thank you.

Title:
  Captive portals may corrupt apt translation indices

Status in “apt” package in Ubuntu:
  Confirmed
Status in “apt” package in Debian:
  New

Bug description:
  I have an adsl modem which returns an html page if the adsl link is
  broken. This page ends as the content of the apt cache files stored in
  /var/lib/apt/lists, which breaks apt.

  The only way to make apt work again is to delete all the files stored
  in /var/lib/apt/lists.
