What's the best way to install apt packages from Debian Stretch on Raspbian Jessie?
I'm using Raspbian Jessie but there are a few packages I want that aren't available (but are in Debian Stretch repos). I want to temporarily use the Stretch repo to install them (and any otherwise-unsatisfied dependencies) but without making anything else come from there in the future.
I understand things might not work; etc.; I'm just trying something out on a throwaway install :)
I tried rigging some files (based on this answer) but I got this.. not sure a) how to fix it and b) whether I'm doing things the right way!

More details would be helpful. You are presumably pulling stuff from the ARM arch of Stretch. What packages? And you are getting the gpg error because you don't have the public key, like the error says. Just install it,and the error will go away.apt-cache search debian keyringgives a bunch of choices. You wantdebian-archive-keyring.

As backports has letsencrypt, I recommend using jessie-backports as it brings less new/packages dependencies than drinking directly from stretch.
To use Jessie backports and install letsencrypt from it:
Add to /etc/apt/sources.list:
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free
The run:
apt-get update
As for installing the key, I confirm you can do:
gpg --keyserver pgpkeys.mit.edu --recv-key 8B48AD6246925553
gpg -a --export 8B48AD6246925553 | sudo apt-key add -
and also with the key 7638D0442B90D010
gpg --keyserver pgpkeys.mit.edu --recv-key 7638D0442B90D010
gpg -a --export 7638D0442B90D010 | sudo apt-key add -
And finally to install letsencrypt:
apt-get install -t jessie-backports letsencrypt

For me, the easiest way was run:
aptitude install debian-keyring debian-archive-keyring
No more errors :)

Didn't work for me in the case of Ubuntu Artful. The solution given at raspberrypi.stackexchange.com/a/60051/87676 worked.

I was only able to succeed after combining both Cristian Deluxe and Rui F Ribeiro answer. (I've mark their answered correct as it is their original work)
Append the following text to /etc/apt/sources.list
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free
I had to install the debian-keyring and debian-archive-keyring
apt-get install -y debian-keyring debian-archive-keyring
Install the GPG keys.
gpg --keyserver pgpkeys.mit.edu --recv-key 8B48AD6246925553
gpg -a --export 8B48AD6246925553 | sudo apt-key add -
gpg --keyserver pgpkeys.mit.edu --recv-key 7638D0442B90D010
gpg -a --export 7638D0442B90D010 | sudo apt-key add -
Finally performed the apt-get update
apt-get update
only after the above steps, could I perform the install of the packages in the backports.

For me, the easiest way was run:
aptitude install debian-keyring debian-archive-keyring
No more errors :)

Didn't work for me in the case of Ubuntu Artful. The solution given at raspberrypi.stackexchange.com/a/60051/87676 worked.

I was only able to succeed after combining both Cristian Deluxe and Rui F Ribeiro answer. (I've mark their answered correct as it is their original work)
Append the following text to /etc/apt/sources.list
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free
I had to install the debian-keyring and debian-archive-keyring
apt-get install -y debian-keyring debian-archive-keyring
Install the GPG keys.
gpg --keyserver pgpkeys.mit.edu --recv-key 8B48AD6246925553
gpg -a --export 8B48AD6246925553 | sudo apt-key add -
gpg --keyserver pgpkeys.mit.edu --recv-key 7638D0442B90D010
gpg -a --export 7638D0442B90D010 | sudo apt-key add -
Finally performed the apt-get update
apt-get update
only after the above steps, could I perform the install of the packages in the backports.

More details would be helpful. You are presumably pulling stuff from the ARM arch of Stretch. What packages? And you are getting the gpg error because you don't have the public key, like the error says. Just install it,and the error will go away.
apt-cache search debian keyringgives a bunch of choices. You wantdebian-archive-keyring.– Faheem Mitha

Better using the backports
deb http://http.debian.net/debian jessie-backports main– Rui F Ribeiro

@RuiFRibeiro Depends whether they are available in backports.

@FaheemMitha I don't know how to "Just install the key" and I've failed at Googling to find out how :( One page suggested doing
apt-get install debian-keychainwhich didn't appear to solve it– Danny Tuppeny
Apr 3 '16 at 17:55
@RuiFRibeiro The package I want
letsencryptis indeed there; though I don't know the difference. Sounds like a better choice, but question remains, how can I get my Pi to use it?– Danny Tuppeny
