I originally had a problem installing packages on a Raspberry Pi 2 Model A with an older version of Raspbian. So downloaded the July 2019 of Raspbian Buster Lite, and it installed ok. But it has the same problem with installs:

sudo apt update
Get:1 http://raspbian.raspberrypi.org/raspbian buster InRelease
Get:2 http://archive.raspberrypi.org/debian buster InRelease
Err:1 http://raspbian.raspberrypi.org/raspbian buster InRelease
  Undetermined Error [IP: 80]
Err:2 http://archive.raspberrypi.org/debian buster InRelease
  Undetermined Error [IP: 80]

and it when I try to install packages it cannot find them. For example

sudo apt install python-pip
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package python-pip

It's on Wifi and it can fetch webpages with wget. I have tried

sudo apt update --allow-releaseinfo-change

but it doesn't help.

    Whatever your problem actually is, it is obvious that your network is incorrectly setup because it is looking on your local network. Forget update - get the internet working first. – Milliways Sep 29 '19 at 11:30
  • "It's on Wifi and it can fetch webpages with wget" - are you behind an HTTP proxy? – Dmitry Grigoryev Sep 29 '19 at 14:40
  • Thanks Both. No HTTP proxy AFAIK. Traceroute gives: traceroute to ox.ac.uk (, 30 hops max, 60 byte packets 1 dsldevice.lan ( 8.881 ms 8.367 ms 12.129 ms 2 * * * etc. – Phileas Sep 29 '19 at 16:14
  • Traceroute to ox.ac.uk isn't important. Try traceroute to raspbian.raspberrypi.org. – Ingo Sep 29 '19 at 16:54
  • @Ingo traceroute to raspbian.raspberrypi.org (, 30 hops max, 60 byte packets 1 dsldevice.lan ( 14.627 ms 14.072 ms 13.582 ms,2 * * *, 3 * * * etc. But not sure why the Pi's IP address does not show in this route. – Phileas Sep 29 '19 at 17:40
