All reports of vcs-field-not-canonical for the archive. The extended description of this tag is:
The VCS-* field contains an uncanonical URI. Please update to use the current canonical URI instead. This reduces the network bandwidth used and makes debcheckout work independent of the port forwarding and redirections properly working.
The definition of canonical used here is the URIs announced by the Alioth admins (see reference).
Note that this check is based on a list of known URIs. Lintian did not send an HTTP request to the URI to test this. Should the canonical URI have changed, please file a bug against Lintian so the check can be updated accordingly.
Refer to https://lists.debian.org/debian-devel-announce/2011/05/msg00009.html for details.
This tag has not been emitted in any package tested by Lintian.
