Raspbian Jessie is very, very old. Those 404 errors are most likely from the fact that even Raspberry Pi no longer supports the release.

Normally we'd suggest an in place upgrade but you're behind by a few releases so you will need to start fresh with a new Raspberry OS install. You can back up your Pi-hole configurations to save them and restore that when you have a new Raspberry OS set up.

In addition, Jessie is not supported by Pi-hole either.

To back up your Pi-hole configuration, use the web admin GUI > Settings > Teleporter function.
