[Bug 1829631] Re: Upgrader shows "Forbidden" error in release notes window

[Oliver Gerlich]

No, the page successfully loads for me now, and also the updater shows
the release notes. So this problem appears to be fixed.

Title:
  Upgrader shows "Forbidden" error in release notes window

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  I started a release upgrade from 16.04 to 18.04 as described in the BionicBeaver Release Notes, ie. enabling update notifications and then running "update-manager -c" and clicking the Upgrade button.
  A window then appeared titled "Veröffentlichungshinweise" (German for Release Notes) with an error message:

  
  Forbidden

  You don't have permission to access /ubuntu/dists/bionic-updates/main/dist-upgrader-all/current/ReleaseAnnouncement.html on this server.
  Apache/2.4.18 (Ubuntu) Server at archive.ubuntu.com Port 80

  
  I cancelled the upgrade and restarted it, and ran Wireshark this time. It showed that the URL "http://archive.ubuntu.com/ubuntu/dists/bionic-updates/main/dist-upgrader-all/current/ReleaseAnnouncement.html?lang%3Dde_DE%26os%3Dubuntu%26ver%3D18.04.2%20LTS" was accessed which resulted in an HTTP 403 error response.
  Opening that URL in Firefox indeed leads to such an error page. Opening the URL without the parameters (ie. without the part after the question mark) leads to actual release notes.
