When I boot up 32-bit Ubuntu 18.04.5 on my i686 32-bit machine, why am I prompted to upgrade to Ubuntu 20.04.1 LTS...which, as I understand it, is a 64-bit OS? Surely the code is smart enough to tell that my machine will not run a 64-bit OS.

  • What do you see when you type uname -m into the terminal? –  Dec 16 '20 at 01:21
  • Note: if you scroll down the comments in my answer, you'll note the initial bug report on this upgrade being offered, then a subsequent re-filing by Brian Murray of Canonical because the issue still occurs.. In most cases offers won't occur, but there are still machines were the offer is made (but it won't allow upgrade.. so no harm is done). I still see it on occasion on my ibm thinkpad t43 running Lubuntu 18.04.5 LTS – guiverc Dec 16 '20 at 01:39
  • Typing uname -m into the terminal returns 'i686'. – user517647 Dec 16 '20 at 03:22

    Wouldn't it be simpler to turn off notifications about new Ubuntu versions in Software & Updates > Updates = Never – graham Dec 16 '20 at 09:43

You can try, but it will fail immediately after processing the upgrade starts. The pre-flight checks determine you can't be upgraded and display this message:

Sorry, no more upgrades for this system

There will not be any further Ubuntu releases for this system's 
'i386' architecture.


Updates for Ubuntu 18.04 will continue until April 2023.

I just tested in an i386 18.04 container.
