Package: aptitude Version: 0.6.11-1+b1 Since 20 March jessie repositories (except LTS) have been removed from the official debian mirrors and are now archived at archive.debian.org, see following mailing list post
https://lists.debian.org/debian-devel-announce/2019/03/msg00006.html The post says that amd64 architecture is included in LTS, however all packages from jessie-backports have disappeared after aptitude update. Is this intentional? I have temporarily switched jessie-backports to archive.debian.org but it needs to disable the expiration check using -o Acquire::Check-Valid-Until=0 In addition I also use devuan jessie on another machine and this problem breaks jessie-backports for devuan, which has no archive.
