sudo apt-get update fails to securely connect to repositories, cannot update anything

I reinstalled Ubuntu Gamepack after accidentally wiping it from my SSD, and I needed to update GNOME to properly boot into it.

I've looked at several other threads and tried those solutions, but nothing has panned out for me. I have some functions that aren't working for me, such as my mouse disconnecting after a certain amount of time, all audio in/out devices not registering after restarting Discord, among other software issues.

If nothing else pans out, I'm considering reinstalling, although that may create more problems than it solves.

Here is the error I'm getting:

Why do you have so many package repos? I get having a few additional ones... but first consider if you really need all of those, and remove the ones you don't need. If you really want to update even though it is insecure, you can, _but it is insecure, so you probobly shouldn't_. See [this other question](https://askubuntu.com/q/732985/1438484) that explains how to bypass the security warning.

I don't know why either, I'm new to Linux. I also have not done much inside the terminal, so apologies if I'm a bit confused. I've tried what you have suggested, and this is what I got: https://pastebin.com/jkyuQvwd

Many of the PPAs weren't added by you directly but added when you *installed* some software (Chrome, Opera, Skype, CUDA/Nvidia, ...). Of those Opera and Skype have problems. I suggest you google both error messages and then you'll learn something new :) (it's just one command to retrieve the missing or expired keys). There's one you added that is obviously wrong, just remove it (and 'ppa-purge' is in the official repos, no need to add a PPA anyway).

You have to open Software & Updates (`software-properties-gtk`) and then disable repositories for Skype and Opera. Then retry running `sudo apt-get update`.

I have done as you said N0rbert, and now I can update some items. I'm getting signature errors, but I think I can figure it out from here. I'll comment again if I need any additional help

Well, I'm coming back again. I'm using the same fork of Linux as last time, and it's says something along the lines of "UbuntuGamePack doesn't have an official release file. updating can't be done securely, and we disabled it." I'm using this on a USB stick, so that may be the issue. I'll update this when I test this on my PC

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.
