LZMA error regarding data corruption for linux-firmware update on fresh install of Ubuntu

in flag

I recently installed Ubuntu 20.04.3 LTS on my second SSD in my desktop (first SSD is running Windows 10). The install seemed to have gone well, but I noticed when I try and perform a software update, the installer seems to get stuck on linux-firmware. More details yield the following images:

As you can see, a LZMA error pops immediately.

Another image of it with the final lines of information. It usually terminates after here and says something along the lines of failed to install/update.

What's causing these errors? Why is the data already corrupt? I believe I installed everything correctly (PC uses legacy BIOS not UEFI), and the operating systems are on different SSDs. This is my first serious foray into Linux. I've normally been a Windows and MacOS user, but I am wanting to use Linux for my work and productivity, and just have Windows for gaming.

Try `sudo apt clean` followed by `sudo apt update && sudo apt full-upgrade`.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
