Updates on my Ubuntu 16.04 system are failing to load. I have run apt-get update to no avail. I get a message "Failed to download repository information" 8-8-18 10:25. And I'm pretty sure I will be told off for adding the following as it's probably in the wrong place. I have tried the following:
Assure cdrom is unchecked then cut and paste entire set of below commands
sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old_`date '+%Y%m%d_%H%M%S'`
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update
The above has made no difference. The system still rejects updates. I'm completely stuck.
