Comment 116 for bug 1835660

Hi
I have this issue when I try to boot USB installation pendrive with Ubuntu 20.04.1 live server made from ISO available from the official webpage.
I downloaded ISO two times, I sha256 its content and compared to value stored in the SHA256SUMS file.
I want to install Ubuntu on my PC next to Windows 10 (dual-boot).
My PC is 4790k, 16GB RAM, GTX1080, multiple hard drives, system disk is SSD.

How can I cope with this issue? What can I do to omit it or to resolve it?
The "Initramfs unpacking failed: Decoding failed" message pops up just after the GRUB menu disappears.
Please help, I would really like to run the Ubuntu server on my computer.

Best regards
