Hi Crady,
It seems that Wheezy and Jessie (except LTS) were removed from mirrors
https://lists.debian.org/debia…nce/2019/03/msg00006.html
You can try this:
https://www.lucas-nussbaum.net/blog/?p=947
Leave just this two lines in your sources.list:
Code
deb http://archive.debian.org/debian/ jessie-backports main contrib non-free
deb-src http://archive.debian.org/debian/ jessie-backports main contrib non-freeAnd execute command:
Code
echo 'Acquire::Check-Valid-Until no;' > /etc/apt/apt.conf.d/99no-check-valid-until
Bear in mind that file openmediavault-kernel-backports.list in location /etc/apt/sources.list.d may contain disabled mirrors also.
Good luck!
