What's the best way to install apt packages from Debian Stretch on Raspbian Jessie?












4














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!



W: GPG error: http://ftp.uk.debian.org stretch InRelease: The

following signatures couldn't be verified because the public

key is not available:

    NO_PUBKEY 8B48AD6246925553 NO_PUBKEY 7638D0442B90D010

  • 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 keyring gives a bunch of choices. You want debian-archive-keyring.

  • @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-keychain which didn't appear to solve it

  • @RuiFRibeiro The package I want letsencrypt is 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?

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 :)

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.

    I saw this but the presence of a .mit.edu domain makes me wonder whether that's the right thing? (and I have two keys there?)

    For me, the easiest way was run:



    aptitude install debian-keyring debian-archive-keyring


    No more errors :)

    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.
