Hello I am using ubuntu 21.04 and everytime I go to do sudo apt update I I get E: Error reading cpu table. I have no idea how to fix this. If anyone can help that would be great. Thanks!

It's easiest if you provide a full paste of the command & error message. A quick scan online and some posts indicate it's an issue with a corrupted *file-system* which is easiest to fix by booting a *live* system (eg. installation media & use "Try Ubuntu"), and file-system check (`fsck`) via command or GUI tool. Others indicate it's because of an interrupted install and fixes are more varied.

Hello thank you for your reply. I am a bit confused on what you are saying, probably cause I am new to Ubuntu and new to linux in general. If you can explain it more for a noob like myself that would be great.

You haven't said if you were using a Ubuntu 21.04 Desktop, or Ubuntu 21.04 Server system, nor provided a full copy/paste of the error message. I would boot *live* media (eg. Ubuntu installation system & use the "Try Ubuntu" option) and perform *file-system* checks there (GUI or command tools can be used). This isn't Ubuntu/Linux specific detail; *live* media was available with Windows XP thru 10 but is expensive & thus rarely seen (available to OEM/enterprise). As I cannot see the full command & error message, I'm unwilling to provide specific advice, only generic advice that can do no harm.

fyi: `fsck` or the file-system check command is called `chkdsk` in DOS/windows... it doesn't actually check a disk, but checks a file-system for *logical* errors that exists on a disk/partition/storage-device.. It doesn't check for bad sectors/clusters/inodes/blocks, but only file-system *logical* errors such as invalid pointers etc... If you're familiar with `chkdsk` from microsoft products since 1981; it's the same thing.. Microsoft called it `fsck` too before 1981 (ie. on their Xenix products)

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.
