Error installing Ubuntu on my external SSD

Hi people!

I'm starting my studies in the IT area and I intend to learn a little about Linux.

I've been using Linux on VirtualBox but I intended to install Linux on my external SSD nvme2, but every time I try it gives me an error. I've tried installing Ubuntu more than 4 times and every time it says it can't complete the installation.

After this error I went to gpart and checked if it was being recognized and the external SSD did not appear, however when I go to install and select where I want to install my external SSD appears.

I can save games and various applications on my external SSD but I really wanted to install Ubuntu (or another Linux distro, not necessarily Ubuntu) on my external SSD.

My config:

SSD: Kingston NV2 NVMe PCIe SNV2S/1000G Internal SSD Drive, Multicolour, 1tb

External Case: UGREEN NVMe M.2 Housing USB 3.1 SSD 10Gbps M.2 Case for NVMe PCIe M-Key/M+B Key in 2230/2242/2260/2280

Laptop: IdeaPad Gaming 3 15ACH6/ Ryzen 5 6000H / SSD nvme2 500gb and 16gb of ram.

Does anyone know what the problem is and how to solve it?

thanks,guy
