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:
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.
