expiration of jessie-backports Release files
this seems to be a new issue with the Jessie release.
- in the Release file on archive.d.o  we have
Date: Tue, 12 Feb 2019 20:25:43 UTC
Valid-Until: Tue, 19 Feb 2019 20:25:43 UTC
- in the Release file for wheezy-backports  we have
Date: Wed, 24 Jan 2018 08:51:34 UTC
which causes apt to rightly complain that the Release file is out
of date and refuse to use the package source.
However it would be useful to me to be able to access packages from
that suite from time to time as we phase out our jessie machines.
Are there any plans to remove the Valid-Until lines from the
archive.d.o copy of the Release and InRelease files and re-sign them?
