Since 18.04 LTS, Ubuntu has stopped providing installers for the 32-bit variant. Can I install 16.04 LTS, then upgrade it to 18.04 LTS instead?

I assume the correct command would be:

sudo do-release-upgrade

What will happen if I have unity-greeter installed before the upgrade? Supposedly I should end with the 18.04 version of it, but Ubuntu has discontinued Unity in 18.04. (I did actually use Lubuntu with Unity greeter). Or the whole ubuntu-desktop for that matter?

  • I'm a little confused sorry, but some of the flavors still have 32bit ISO's (eg. Lubuntu 18.04 LTS is available in 32bit, and I'm currently testing the 18.10 Lubuntu 32bit ISO...). Unity is no longer supported by Canonical for 18.04 LTS (but still is for 14.04 LTS & 16.04 LTS) and has moved to 'universe' or community-supported, so Unity will still work on 18.04 in the same way LXDE, MATE, XFCE does. ubuntu-desktop in 18.04 means GNOME & no longer Unity (Unity is found in ubuntu-unity-desktop in 18.04 LTS) – guiverc Aug 02 '18 at 12:39

    I don't understand why you have changed your LXDE desktop into a Unity one; that's the main reason of Lubuntu, using the light desktop LXDE -> so if you want Unity, just take the standard Ubuntu and replace Gnome – damadam Aug 02 '18 at 12:43

Lubuntu and the other Ubuntu community flavours provide both 64-bit and 32-bit iso files.

You can find the iso files and corresponding checksums via this link

releases.ubuntu.com/

You've asked a number of questions ...

Some flavors still have 32-bit ISO's (eg. Lubuntu 18.04 LTS has)

Unity is no longer supported by Canonical for 18.04 LTS (but still is for 14.04 LTS & 16.04 LTS) and has moved to 'universe' or now in the community-supported repository. Hence Unity will still work on 18.04 in the same way LXDE, MATE, XFCE does.

ubuntu-desktop in 18.04 means GNOME & no longer Unity, with the Unity DEsktop found in the ubuntu-unity-desktop package in 18.04 LTS
