NO_PUBKEY error after attempt to update to stretch repo

[BloggerBust]

Hi, The following is not specifically an issue with your updater. It is an issue with updating the kano though and I am hoping that you might be able to help me get this sorted out.

I have the kano complete. The kano was on the jessie repo, but I needed a package that was only available on stretch. I updated /etc/apt/sources.list

deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi                                                                                                   
deb-src http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi 

After running apt-get update / upgrade and dist-upgrade I received a gpg invalid sig error. So I deleted the sig with sudo apt-key del 0EA88FEDB9B35AE4A2FB9526B1FE0458DEA56695 and then tried getting a new key with sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 5243CDED. I found this command and the key id 5243CDED the updater source code. Now when I run apt-get update I get a no PUBKEY error

Also, if I try to run the kano-updater I get the following error:

How can I correct this issue so that I can update my kano using the stretch repo?

Thank you kindly for your time.

I was able to get the kano jessie repo key installed again via

wget -qO - http://repo.kano.me/archive-jessie/repo.gpg.key | sudo apt-key add - 

Once the key was updated I ran an update. It is back to complaining about the signature being invalid:

I believe that the problem is that kano needs a jessie repo, but the /etc/apt/sources.list is pointing to a stretch repo. Is it possible to have the system use both jessie and stretch repos to satisfy the kano packages as well as the stretch packages that I need?

[BloggerBust]

I tried adding the following to /etc/apt/sources.list:

deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi                                                                                                    
deb-src http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi                                                                                                
deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi                                                                                                   
deb-src http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi

Then ran another update:

$ sudo apt-get update
