update-manager fails to download release notes with apt-cacher-ng

[Andy Whitcroft]

Binary package hint: update-manager

TEST CASE:
1. use lucid with the latest update (but with the normal apt-cacher-ng)
2. run apt-cacher-ng on this machine
3. point proxy to apt-cacher-ng and run "update-manager -d"
4. verify that no release update appears

5. install the new apt-cacher-ng from lucid-proposed
6. repeat 2,3 and verify that it works now

Now that update-manager is correctly honouring the apt Proxy configuration update-manager -d upgrades to the next development release no longer work. The download of the DevelReleaseAnnouncement fails. This seems to occur because the request has a ?lang=<foo> suffix.

Investigations show that this is actually fixable via configuration changes to apt-cacher-ng. Shoving this over there for resolution.

Attaching a proposed patch for apt-cacher-ng which seems to sort the problem out for me. This diff also includes a conversion to debian 3.0 (quilt) format so it is slightly bigger than required.

[Andy Whitcroft (apw)]

Here is the same patch for Lucid.

[Andy Whitcroft (apw)]

@ubuntu-sponsors -- in #3 and #4 above are proposed debdiffs for apt-cacher-ng to allow update-manager -d mode upgrades to the next release to work. Without these update-manager is unable to get the release notes and refuses to update the users system.

I made ReleaseAnnoucement have the \\? as well: "ReleaseAnnouncement|(\\?.*)"

and uploaded to maverick. many thanks. We should probably SRU this too once the fix in maverick is confirmed to work.

This bug was fixed in the package apt-cacher-ng - 0.4.7-1ubuntu2

---------------
apt-cacher-ng (0.4.7-1ubuntu2) maverick; urgency=low

  * convert package to 3.0 (quilt) format
  * pull existing stat::stat patch over to quilt patch
  * update-manager -d requires access to the DevelReleaseAnnouncement
    accessing it with a ?lang=foo suffix. Add this to the persistant
    files list. LP: #601883.

Accepted apt-cacher-ng into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

@martin -- re-installed the Lucid -updates version and confirmed that the update-manager -d was unable to download the release notes. Updated to the Lucid -proposed version and confirmed that the update-manager -d was then able to download the release notes and start the upgrade.
