OS update fails

I have a new pi-top[4], pi-top screen, keyboard and robotics kit. When I tried to run the first Further tutorial I was told to upgrade the OS, so I did:

System tools > Check for updates then Update now

This generated loads of errors such as:

Err:1 http://raspbian.raspberrypi.org/raspbian buster/main armhf hostapd armhf 2:2.7 …
404 Not Found [IP: 93.93.128.193 80]

Help!

I got good feedback from support@pi-top.com

sudo apt update
sudo apt dist-upgrade -y

Then update worked and I can connect to the pi-top.

@johnbarr Great to hear that this fix worked for you. Just to add for anyone else, here is the link to our guide for anyone having a similar issue.
