I have installed Ubuntu 18.04 (Bionic Beaver), which my PC was upgraded to after it had 32 bit Ubuntu 16.04, because the system suggested me to do so.

Today I discovered that there's no .iso with Ubuntu 18.04 LTS 32 bit on the official Ubuntu sites, including http://releases.ubuntu.com/18.04/.

Also, I have read a little bit about mini.iso aka Netboot. But, for Ubuntu upgrade I haven't used a piece of extra media like USB or CD, it went in a usual desktop environment. Related: How come Ubuntu 18.04 LTS has a 32bit iso installer?

The question is: why I have an official Ubuntu 18.04, which does not exist on the official Ubuntu download webpage? How it works?

uname -a output:

Linux mathway-GA-970A-DS3 4.15.0-112-generic #113-Ubuntu SMP Thu Jul 9 23:41:06 UTC 2020 i686 athlon i686 GNU/Linux

There is no Ubuntu 18.04 LTS desktop ISO, that was announced years ago and hasn't changed (wasn't any for 17.10 either).

Yes, Ubuntu 18.04 LTS is supported on x86 (flavor ISOs exist, plus netboot), but there is no i386/x86 desktop ISO except for amd64.

Some flavors (e.g. Lubuntu & Xubuntu) supported 18.10 fully for x86, and even continued into the 19.04 cycle for alpha ISOs (last ISO was very early Dec-2018 for Xubuntu, late Dec-2018 for Lubuntu) which had you installed either, your system would have had all upgraded packages for the life of 19.04.

The x86 upgrades were disabled completely just prior to 19.10's actual release (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1845714)

If you're using x86/32-bit though, your best supported bet is 18.04 LTS, as it'll have 5 years of support for main repository (server, default desktop) and 3 years for flavors.
