[Bug 1290270] Re: apt-get uses an unreliable transfer protocol

[Erick Brunzell]

I subscribed and added the release-upgrader tag.

I use only wired connections so I've never been able to test that aspect
of the release upgrade but I'd always assumed that a check would be run
for a wired connection before beginning the upgrade.

If Brian Murray is reading I'll bet he'd know :^)

Title:
  apt-get uses an unreliable transfer protocol

Status in “apt” package in Ubuntu:
  New

Bug description:
  I tried to "sudo apt-get update" Clean Ubuntu Gnome 13.10 using an
  unreliable mobile Internet connection. The goal was to upgrade to
  Ubuntu Gnome 14.04 beta.

  The connection works for a minute and then dissapears, then comes
  back.

  If the partial downloaded index files are changed, there is no check
  that they are correctly downloaded from the server (no date stamp,
  size) and I got the error:

  W: GPG error: http://se.archive.ubuntu.com saucy-updates Release: The
  following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu
  Archive Automatic Signing Key <ftpmaster at ubuntu.com>

  After cleaning up "/var/lib/apt/lists/*" I was able to issue another
  apt-get update, but I'm still not able to download the indexes.

  There need to be a timeout (20s) and retry (many). Even looking up
  must have retries. There need to be a check for changed index files.

  Then the goal was to issue "sudo apt-get upgrade" and then upgrade to
  14.04 beta. With this I haven't succeded yet.
