I'm using a docker image as a base for my own development that adds the jessie backports repository in its Dockerfile and uses that to install a dependency. This image uses the following command to add the repository:
echo "deb http://ftp.debian.org/debian jessie-backports main" >> /etc/apt/sources.list
The problem is that fetching packages from the backports repository now fails with the following error (this used to work previously):
W: Failed to fetch
http://ftp.debian.org/debian/dists/jessie-backports/main/binary-amd64/Packages
404 Not Found
W: Failed to fetch
http://deb.debian.org/debian/dists/jessie-updates/main/binary-amd64/Packages
404 Not Found
I looked on that server, and those paths are indeed not present there.
I tried to figure out on the Debian backports site whether this particular repository should still be available, and I didn't find any indication that this was deprecated or something like that.
Is this a temporary issue with the repository, or is the jessie-backports repository not available anymore? And if this is not a temporary issue, what options do I have to use this or an equivalent repository without upgrading to the newer Debian stable version?
