Ubuntu might be great and frequent software updates might be very helpful in keeping the system up-to-date and secure. But my problem is,
- the software updater is causing my system to freeze and I have to restart the system to frequently.
- even if (1) is not correct i.e the updater is not causing the system to freeze, another problem I see is after doing the update it's asking me to restart the system for most of the updates. And if I don't restart, the system is freezing again. And I have to do a restart to over come the system freeze.
- even if not for (1) and (2), i am using the system for development activities and so security and frequent updates are not my priority. I have several VM's and docker containers running on the machine, so my priority is the keep the system running for weeks and months with out restarting. And I suspect, software updater is hindering this.
Is there an easy way to disable these update prompts entirely. Please provide your views/answers.
A screenshot of software updater I am referring to is below.

This is current least update preference I could set -

Edit - Thanks to Roman Riabenko for suggesting to check the links on comments which in turn suggest to check unattended upgrades. But this does not seems to be the case with 20.04.1.
