Owen5819 Interesting, in a tooth-gnashing sort of way. The installation is failing at an odd point, without an error message.
Let me suggest a look at the basics:
(1) Is your BIOS set to UEFI rather than MBR/Legacy? Solus requires UEFI, but Ubuntu does not.
(2) Is Secure Boot disabled in BIOS/UEFI? Solus requires that Secure Boot be disabled, but Ubuntu does not.
(3) Is your SATA set to ACHI rather than RAID? Solus works better with ACHI, but Ubuntu is agnostic in my experience.
(4) Is the disk onto which you are trying to install set to GPT formatting? It should be because you are using Ubuntu, but it is worth checking just in case, because Ubuntu also allows MBR/Legacy installation.
(5) In your Live session, is wifi working? Is wifi shown as working during the installation process? Installation usually requires a second sign-in to connect. If wifi is not working correctly, the installation process will not connect to your ISP to get time zone information, and that might explain the odd "US: none" message.
(6) Are any of your Ubuntu partitions protected/encrypted? If so, that might account for the freeze at "Create new ESP on /dev/sda".
Take a look at your target drive with GParted in Ubuntu. You should (I think) see three partitions -- the ESP boot partition, a swap partition, and a large data partition, typically formatted with EXT4. That's the norm, I think, and that's what I see on my Kubuntu installation. If the target drive shows a bunch of other partitions (artifacts from old installations), that might account for the fact that the Solus installer runs into problems trying to wipe/reformat the drive. Check and let us know. As @nolan suggested, you might want to manually delete the Ubuntu partitions before proceeding with the installation, but I would suggest that as a last, not first, step.
It might be helpful to others looking at this thread if you would provide information concerning your discrete graphics card, if any. The AMD Ryzen 5 5600G CPU has onboard Radeon graphics, but if you also have a discrete graphics card, it would be helpful to know.
It is possible that the CPU/GPU combination is not supported by the 5.13 kernel, which is the Solus ISO's kernel. The Ryzen 5 5600G was released in April 2021, just a few months before the 5.13 kernel was released (July 2021), so it is possible that 5.13 doesn't have the right drivers for the Radeon graphics. I would have suspected issues with the Live session if that were the case, but I don't think that we can rule out that issue.
It would also be helpful if you could identify your wifi adapter.
Edit/Update:
Owen5819 Check "Use LVM in the new location" but not "Encrypt the new installation."
LVM problems have been reported in the forum, so you might consider installing without LVM and see if that makes a difference.
