For the past 5 years, I have been using Ubuntu 14.04 LTS. During that time, I didn’t face any unwanted internet data consumption issues. Recently I installed Ubuntu 20.04 LTS. I haven't installed any other software yet. I configured auto update settings as below. Ubuntu 20.04 software & update settings
Even after the above settings, Ubuntu 20.04 consumes around 1 GB of internet data within a few minutes in idle state (not browsing anything). I am using Wi-Fi hotspots internet data from mobile. Please help guide me to stop this huge unintended consumption of internet data by Ubuntu 20.04. Thanks.
