The installer complains about a checksum issue. This indicates that the installer was probably not downloaded correctly or the file was corrupted in some other way. You should try to download the ISO from here again [1]. And if it happens again, try to verify the ISO by following this guide [2] before installing.

The Ubuntu ISO could be wrong. Look at the checksum error message. Try again to download a Ubuntu ISO. I have several Ubuntu Server instances running on my Proxmox nodes without any problems.

Hello,
"I am installing ubuntu-24.04.3-live-server-amd64.iso on Proxmox Linux 6.8.12-9-pve #1 SMP PREEMPT_DYNAMIC PMX 6.8.12-9 (2025-03-16T19:18Z) x86_64 GNU/Linux and it generates an error. I downloaded the ISO file from different Ubuntu mirrors. After a successful download, I verified the checksums.

thanks in advance.
 
I had a similar problem where the installer would hang on "Installing Kernel" and then fail. I tried the same installer iso (verified the hash) on another instance of Proxmox running version 8 - same result. I tried changing the VM hardware configuration to about every option I could - same result. Then as a test, I spun up an XCP-ng server and had the same results there as well.

Turns out it was something with the default mirror the installer wants to use. I changed to the Pilot Fiber mirror and the install completed without issues on Proxmox. Hopefully this helps anyone else experiencing this.
