404 error is not "I cannot see the server", but "the server cannot find
the file!"


So it is NOTHING to do with your network connection!

Sorry that was a red herring.

I have seen this occasionally when distros are being updated.

Hmm.. Jessie was last updated on the 21st..

y'know I BET that somehow you are using a proxy server and it has cached
an incomplete and old version of what is on that server.

One possible way - I'd ask others to comment - to circumvent that is to
use https instead of http.

So modify the remote sources.list to use https.

proxy servers usually pass that straight through.

You will get errors from:


  https://raspbian.raspberrypi.org/raspbian stretch InRelease
   Failed to connect to raspbian.raspberrypi.org port 443: Connection
refused

but my pi DID connect to archive.raspberrypi.org

So once its done that, go back to the old sources.list and try and
install whatever you need.

Its bloody hard to circumvent mobile phone ISP proxy servers. Pain in
the arse.
