"ubi-partman failed exit code 141" error while installing Kubuntu 21.04

I'm trying to switch from Windows 10 to Kubuntu 21.04 but, I keep getting this error:

ubi-partman failed exit code 141

After getting done filling out the Software options in the Kubuntu 21.04 installer, my mouse shows that something is being loaded. Then my fans kick in, and the error ubi-partman failed exit code 141 gets thrown. I've tried installing about 5 times, and this happens every time.

If this helps at all, my laptop is an ASUS TUF GAMING. Secure Boot and Fast Boot are both not enabled.

Here is where I downloaded the ISO file: https://kubuntu.org/getkubuntu/

Here is the exact ISO file/link I downloaded: https://cdimage.ubuntu.com/kubuntu/releases/21.04/release/kubuntu-21.04-desktop-amd64.iso

I verified the integrity of my ISO file by installing Kubuntu 21.04 using the same ISO file on a VM.

Applications used to flash:

• BalenaEtcher -- Yielded same result
• Rufus -- Yielded same result

Currently Testing if RST/RAID is enabled and disabling it, will update with results.

Methods for disabling RST:

• Disable RST for Installing ubuntu 20.4 Dual boot

or

• https://www.intel.com/content/www/us/en/support/articles/000027232/technologies/intel-rapid-storage-technology-intel-rst.html

Maybe this is why I get this problem?

The solution proposed in this article also failed: https://programmerah.com/solution-to-ubi-partman-failed-with-code-141-when-installing-ubuntu-3551/

Although it didn't work, this might be useful information:

None of this stuff is really important, just addressing some concerns and questions from comments.

• Why do you want Kubuntu/Ubuntu/Linux?

  I wanted Linux because I was first introduced to Linux in a Cybersecurity class and joined a club called CyberPatriot. Through this club I was assigned Ubuntu to have to secure, and quickly fell in love with how customizable, and open Linux was, so I decided upon installing a VM just to run Linux and play around with it on my own Windows machine. Although, I could never actually install Linux as I had too much stuff on my Windows machine, luckily this is a completely new PC so, I can finally fully enjoy Linux. I also feared that things I needed and used daily weren't going to be supported on Linux and luckily, they are all supported.

  I also had only 8 GB of ram about 7.8 GB usable RAM and Windows used 5 GB of that, keep in mind this laptop is for gaming and why that would become an issue, of course that can be fixed slightly (I tried everything I could) without Linux but, there was also a ton of intrusive applications built into Windows because of ASUS that made me go ahead and go through with just installing Ubuntu, I chose Kubuntu because of it utilizing KDE instead of GNOME, which I've heard was more customizable as trying to customize with GNOME becomes very difficult.

• Addressing recommendation to use Kubuntu 20.04.

  I honestly just don't like it as much as Kubuntu 21.04 visually which might be a dumb and shallow reason but yeah, I like Kubuntu 21.04s look a lot better. Also, yeah I had to deal with the nomodeset issue before within a VirtualBox VM luckily, Kubuntu 21.04 seems to interact well with my drivers at least for now.

Solution 1:

https://community.acer.com/en/discussion/608239/disabling-rst WORKED!

I needed to disable RST through my BIOS. I thought this setting wasn't available on my BIOS somehow, so I neglected this solution, but I finally found the setting.

Thank you all for the help!
