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?

  • sudo apt-get upgrade has certain limits it works within, if you want to install all upgrades use sudo apt-get dist-upgrade. The man apt-get will tell you "dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages..." (read it yourself for all the details) – guiverc Jun 21 '20 at 07:45

  • Refer to https://help.ubuntu.com/community/Repositories/Ubuntu (see Adding Extra Repositories for the details) for Canonical Parters; and no, in most cases, it won't provide extra security updates as provide alternate software - not upgraded packages to software you already have. (It maybe possible that if you hardware came pre-installed with Ubuntu, that may be necessary, but if you downloaded & installed it yourself I can't see that as necessary) – guiverc Jun 21 '20 at 08:03
