Status changed to 'Confirmed' because the bug affects multiple users.

Can you explain exactly what you saw? The ubiquity logs attached to your bug report don't show a crash.

> can only access line command labeld GRUB GNU 2.0-19

Which seems to be the version of grub from saucy (Ubuntu 13.10).

[Dave (cowboydave251)]

Hello, Steve. Thank you for looking into this for me.

I was attempting to replace Ubuntu 13.10 with 20.04. After downloading the
.iso file and Rufus onto my Win7 machine, I created a bootable thumb drive
that passed verification.
During the install process, I selected the OEM install. Everything seemed
to be going well. The GUI cam up with its red background and wire frame
kitty cat and it seemed like it was near the end of the process. As I was
answering some questions... user name, etc. I was halted by a big white
pop-up that said:

"We're sorry, the installer crashed...."

The message went on to explain that the problem would be reported and I
would have a chance to add any comments. I closed that pop-up and the
install seemed like it was wrapping up the installation when I was
bombarded with a sequence of other pop-ups, the first one stating that:

"The problem cannot be reported"

followed by several others, each stating:

"Sorry, Ubuntu 20.04 has experienced an internal error."

and one that said:

"The application IBUS Preference has closed unexpectedly"

Ultimately, I was given one last message stating that if the problem didn't
go away, reboot. At that point, the thing -appeared- to be working, but I
didn't try to do anything and opted to reboot. It never came back from
that. Now, all get is a crash on start that takes me back to whatever line
command system it there... grub gnu something 2.0-19. I don't speak GNU,
so I'm DIW right there.

Additionally, I have tried to reinstall 20.04, but after I select type of
install, it just crashes down to the command line again and won't even try
to install or tell my why. At the moment, I'm thinking that there is
something in the 13.10 stuff that it making the 20.04 stuff have
heartburn. If that is the case, I'm wondering if just reformatting the C
drive will fix it.

I have photos of most of the screen pop-ups that occurred,. so if you think
that seeing them and reading the (to me) gibberish on them would help
analyze the problem, let me know and I will forward them.

Thanks for any help.
Dave

Seems like below is what causes installer crash:

>Apr 25 04:02:05 ubuntu ubiquity: umount: /target: target is busy.

I'm having the same problem replacing 18.04 with 20.4, in my case it crashed saying that the disk is currently in use followed by

>Ubiquity: AssertionError: Failed to mount the target: /target

I also have a video of the failed installation flow, I reproduced the problem several times but not the last few times I tried, maybe there is some detail in the flow I'm missing. Let me know if any other info is needed.

[Dave (cowboydave251)]

Do you have any advice for what to do next? I've tried several times to
redo the install, but the install crashes right up front now every time and
dumps me down to GNU command line just a few seconds after I tell it what
type of install I want to do.

I'm thinking of reformatting the partition, then trying it again after the
drive is erased... Good idea?

This may help actually, there is a chance this issue is caused by the existing installation on your disk

[Sithuk (sithuk)]

Ubiqity crashed on me too with the following error.

Ubiquity: AssertionError: Failed to mount the target: /target

I was attempting to install root on zfs. It worked when doing a normal non-zfs install.

I've more information on what I suspect is a regression. Attempting 20.04.1-LTS on an emachines/acer EL1210-09 (Acer DA078l: AMD Athlon LE-1620; nVIDIA nForce 780a MCP (C77 GPU in northbridge), msi GT610-1GD3-L (nVIDIA GF119, 1 GiB VRAM)), the installer would crash consistently if I attempted 3rd-party drivers. 18.04.5-LTS installs without a hitch.
