** Description changed:
Binary package hint: update-manager
When upgrading from hardy to intrepid, update-manager ignores the local
sources.list and downloads everything needed from archive.ubuntu.org.
This is problematic for multiple reasons.
- 1. Some users may have a local or regional mirror that provides faster
downloads than archive. Ignoring sources.list prevents them from using those
local mirrors, possibly causing substantial bandwidth costs.
- 2. During the initial release window for intrepid thousands of Ubuntu users
are going to upgrade. Will archive be able to handle the demand?

3. When upgrading multiple machines in a laboratory or corporate environment,
each machine will download all the packages they need from archive, rather than
allowing a single download via the use of apt-proxy or other related proxy
systems.
Please re-consider this policy decision.

+ WORKAROUND:
+
+ It is possible to disable this check - in DistUpgradeController we see:
+
+ # skip mirror check if special environment is set
+ # (useful for server admins with internal repos)
+ if (self.config.getWithDefault("Sources","AllowThirdParty",False) or
+ "RELEASE_UPRADER_ALLOW_THIRD_PARTY" in os.environ):
+ logging.warning("mirror check skipped, *overriden* via config")
+ mirror_check=False
