apt update issues with debian and whonix templates recently

[Devin Cofer]

Hello all,

Recently my Qubes 4 installation's debian template and whonix templates stopped updating correctly.

Fedora-based templates and Dom0 update fine.

`sudo apt update` on debian template will error when it tries to fetch jessie-backports Release.

....
Err:7 https://cdn-aws.deb.debian.org/debian jessie-backports Release
404 Not Found
Reading package lists... Done
E: The repository 'https://deb.debian.org/debian jessie-backports Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
....

On whonix templates, `sudo apt update` stalls at "0% [Waiting for headers]" for a long time, then proceeds until it hits other errors.

....
Err:4 https://deb.whonix.org stretch Release
Received HTTP code 500 from proxy after CONNECT
Err:5 https://deb.qubes-os.org/r4.0/vm stretch Release
Received HTTP code 500 from proxy after CONNECT
Ign:6 https://deb.debian.org/debian stretch InRelease
Err:7 https://deb.debian.org/debian-security stretch/updates Release
Received HTTP code 500 from proxy after CONNECT
Err:8 https://deb.debian.org/debian stretch Release
Received HTTP code 500 from proxy after CONNECT
....

I typed this out, so excuse any spelling mistakes in the command output.

Thanks for any assistance!

TLDR, comment out that jessie-backports line in apt sources in the
problem templates.

Thank you awokd, I missed that post.

I resolved my Whonix issues by fixing some improper networking configuration that was causing Tor problems.
