Ubuntu Version:
windows 7 and 16.04 LTS and 22.04 LTS
( to test steam, which really is just a side point and nothing to done with 22.04 issue)
It appears the ubuntu 22.04 will not allow you to erase a hard drive if it sees an existing ubuntu version.
I’m testing installing ubuntu on a pc to see if I can run steam games and did the following:
I have a cd with 16.04 and install it alone side windows 7.
upgrade to 18.04 then to 20.?? the to 22.04
installed steam and tested
then seeing that it works fine ( ubuntu and steam)
decided to scrap the install and do a fresh install of 22.04 to remove all of the partitions and only having ubuntu installed ( no windows )
So i booted the 22.04 cd and it only has the standard grub menu
“Try or Install Ubuntu ” etc…
if you select install it runs the install but does not really install 22.04
also it does not ask for language or if you what something else or if you what to erase the drive.
after the 22.04 install completes it what to reboot ( asking to remove the media) and then only bring up version 16.04.
and after several attempts to do an in place upgrade and failing or not starting.
( answering – Yes to msg "18.04 available do you … " --)
( this issue might be that there is 22.04 parts from the install and the upgrade is confused )
( even apt-get upgrade did not work)
solution:
I started over with 16.04 erasing the drive and i’m now in the middle of an in place upgrade to 18.04.
these are the only options from the CD, if you select try or install ubuntu then next thing it does is starts unpacking and load the components , it does not ask anything else ( not language, keyboard, or if you want to erase or keep the files)
I did see another post that stated they too did not see the Erase option.
so right on I’m on 22.04 after using 16.04 to erase the drive, and upgrade thru 18 , 20 and then to 22.04 ( seeing that the only two cd’s i have are of versions 16 and 22)
You then show an image of the GRUB bootloader, which is asking how you want to boot your media?? and doesn’t relate at all to install.
Ubuntu 22.04 LTS had a number of installers, ubiquity used by Desktop, subiquity used by Server, and calamares used by two flavors (the other flavors used the ubiquity installer just as Ubuntu Desktop does). The installer cannot start until a Linux system is actually running, which isn’t the case in your picture, as its GRUB or the boot-loader that starts the boot of Linux.
The unpacking you refer to is unpacking from the squashfs the live system which will be put in RAM, required so you can either TRY (run the session only live) or actually want to INSTALL. Key is the picture you show offered only boot options.
Please do note the oldest release on-topic on this site (in Support and Help) is Ubuntu 22.04 LTS. (Older releases of Ubuntu using ESM are supported by Canonical elsewhere)
Ah, this looks like a misunderstanding to me.
Easily fixed.
Select “Try or Install Ubuntu.” Highlight it and hit <enter>
That will take you to further set of choices, among which is erasing.
The first menu you showed is the bootloader (aka “GRUB”). The bootloader is asking you if you wish to install or rescue or other rare technical tasks. The actual installer hasn’t started yet. (Indeed, the whole Ubuntu system hasn’t booted yet, hence the name “bootloader”.)
The reason for showing you the bootloader is that troubleshooting hardware sometimes requires different boot options. So that capability must be exposed before the system boots. “*Try or install Ubuntu” is at the top and pre-selected because that’s what most folks (including you) want.
I have running 22.04 now, I just posted this in case others had the same issue trying to get from an older version to 22 or 24.
but thanks for replying.
and Yes , i understand that it is the bootloader, it is the only thing that appears when I boot from the CD, so to be clear, when “*Try or install Ubuntu” is selected, it does not show any other menus or options, it just starts installing 22.04 but does not really install it, when it done and what’s me to remove the media and it reboots, it still show 16.04 after rebooting.
so it appears that there is no way to go from 16 to 22 directly.
You can only upgrade from one LTS release directly to the next sequential LTS release. For example, if you are on Ubuntu 16.04 LTS, you can upgrade to Ubuntu 18.04 LTS. However, you cannot skip releases (e.g. jump from 16.04 LTS to 20.04 LTS).If you need to reach a later LTS, you will have to upgrade in stages: first to Ubuntu 18.04 LTS, then to Ubuntu 20.04 LTS, and so on.
It boots into a live session and opens a Desktop.
This allows interested users to explore Ubuntu without installing to disk.
Then, if the user is happy after exploration, installation is a click away.
This image shows the Install icon (which leads to many user options)
