I am using Ubuntu 20.04 LTS.
When I use:
sudo apt-get update sudo apt-get upgrade
in the terminal, my software repository is updated, and the softwares are upgraded by some download. However, when I go to "Software Updater", there are some security updates present, namely:
Generic Linux kernel header, Generic Linux kernel image, etc. (almost worth ~75 MB).
I got confused because these security updates were not downloaded and installed when I ran:
sudo apt-get upgrade
Why is it so?
Should they be downloaded?
Should I also enable (tick) Canonical Partners repository in Software & Updates > Other Software to get security updates?
