In my laptop I installed Ubuntu 18.04 LTS OS as a dual boot OS alongside of Microsoft Windows 10 OS. I stopped the automatic update process. Normally I connecting my laptop with mobile tethering based Wi-Fi hotspot. Recently my laptop consumes more than 1 GB of internet data within few minutes when connecting it without doing any internet access process by manually with frequently. So I tried USB tethering also and I faced same problem. What may be the reasonable causes for my problem and how to resolve it. Guide me to resolve my problem. Thanks in advance.

    "Anyhow I stopped automatic update in software & updates" that does NOT stop snap updates. neither does sudo snap set system refresh.metered=hold snaps WILL update at some point in time. Did you check the online accounts? Those should be "off" by default. Also apport/whoopsie can go to the outside (though not 1Gb :) ) see https://askubuntu.com/questions/93457/how-do-i-enable-or-disable-apport – Rinzwind Aug 08 '19 at 13:58
  • @ Rinzwind : As per your link.. Some answer was to stop/mask the apport service. But, one answer was "do not stop apport, it will create problem if any crash happens". What may be is my right choice? – user1999109 Aug 09 '19 at 05:46
