Something went wrong during the installation of Ubuntu 24.04

[semedilino073]

Hello, I’m really new to Ubuntu. I was trying to install the version 24.04 desktop and I got the message “Something went wrong during the installation”. I had the installation file on a 16 GB flash drive and I would to install it on a 2TB separated disk.
What can I do?

Power off the PC
Boot your installation flash drive into a "Try Ubuntu" live session
Open a terminal and enter:-

[ -d /sys/firmware/efi ] && echo "UEFI" || echo "Legacy"

Hopefully, the response is UEFI
Next, enter this (so that we can see your disk structure)

sudo parted -l

In your reply, please use code tags to legibly display the terminal output.

The first response is UEFI
Here's the second response:

Is this your target disk?
You need to create a partition table so that it is visible to the Ubuntu installer.
In a live session, open Gparted > Device > Create Partition Table > Select GPT
Then, I would expect the installer to find it.

By the way, it is a good idea to remove/isolate other disks to avoid errors.
Only the installer USB and target disk should be active.

Unfortunately, I still get this log:

Not making much progress yet, but never mind, let's see where we are?
During the installation process, when do you see "Something went wrong" message?

Also, in a "Try Ubuntu" session, can you show the current output from:-

sudo parted -l
