Unable to upgrade from 20.04.2 to 20.04.3

I recently bought a Dell Laptop with Ubuntu 20.04.2 pre-installed in it. After my first time login, it did update a few software packages, but I was still at 20.04.2 at the end of it. I tried apt-get update && apt-get upgrade / apt-get dist-upgrade through the terminal, but still no effect.

Considering 20.04.3 is already released end of August, shouldn't I be getting it when trying to do the above update + upgrade? From the GUI 'Software & Updates', I had set Notify me of a new Ubuntu version (For long-term support versions). But even the GUI updater says my software is up-to-date.

Not sure what I am missing here. Here are some details:

lsb_release -a:

@Nmath Yes I understand it is just another point release of the same release. And this is exactly why I am confused why a simple apt update + upgrade is not able to get it. Anyway I updated the full output of apt-get update. And whatever output I already posted for apt upgrade, that is what I am getting still.

How do you have Linux kernel 5.10? This is not the correct kernel for Ubuntu 20.04 for HWE or GA.

The new laptop came with Ubuntu pre-installed in it. And since then I didn't do anything in terms of kernel version. The only update that was done is via a GUI notification that I got that some packages are available for update.

Hmmm... I see one xenial repo that might be problematic but I would expect there to be an error if that is the case. Can you go under `/etc/apt` and check `sources.list` and any other source lists. If you comment out unofficial sources with `#` before each line, then run `sudo apt clean` and then try `sudo apt update` and `sudo apt upgrade` again. You can uncomment the lines after you try this. You can also make a backup of these source lists or just make a note which ones you commented so you can change them back.

So, the master /etc/apt/sources.list is untouched. I do see a bunch of lists under /etc/apt/sources.list.d (created by my laptop OEM and other software). Are you suggesting that I move everything under sources.list.d to a backup directory. Then run `sudo apt clean` followed by `sudo apt update` and `sudo apt upgrade`? After that, I can bring them back? Thank you for looking into this issue and helping me.

You can make a copy to restore it if necessary. I am suggesting to edit the lists and add a `#` before each line that is not an official Ubuntu source. `apt clean` will purge the apt cache and you may get different updates the next time you run `apt update`. If it doesn't work you can just restore the backups or just remove the `#` that you added. If things look really weird after `apt update` and you aren't sure, it won't change anything unless you proceed with `apt upgrade` anyway. If that happens, don't proceed with `apt upgrade` and post the details here in an edit

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
