What should a lay user know about Linux app packaging?

I’m enough of a Linux lay user that I’m not even sure if I’m using the right terminology in the question (feel free to tweak it if needed!). Here’s what I mean:
I’m running Pop!_OS currently, and I have at least one app installed via each of the following methods:
- Deb app from the distro repositories
- Deb deb downloaded from program website
- Flatpak app downloaded from Flathub
- AppImage app downloaded from program website
- Snap app downloaded from the Snap store
As someone who doesn’t really know or necessarily even care to know what’s going on under the hood, these all pretty much work identically for me (with the exception of AppImage which doesn’t integrate into my regular programs menu, and the standalone Deb, which requires manual updating). In fact, for most of the programs on my computer I couldn’t tell you which one they’re sourced from. They all just run like they should.
I’ve looked up differences between all of the options and usually end up finding conversations that go well above my head and get deep into technical details. My question here is basically aimed at cutting through a lot of that depth: what is the important, need-to-know information about these different methods of installing apps? Is there anything I should be aware of if all I’m really going to be doing is running them as a standard, non-power user? Also, if an app is available via multiple methods — is there one that is preferred/better/safer/superior/etc.?

[SOLVED] Tech Support Request: Finding the biggest files of a specific type

Hey Tildes!
I need some help with a specific tech issue, and I'm sure someone here can help me do it way quicker than I would be able to on my own.
General Request
I'd like to be able to scan a directory and find all of the largest files of a specific type (e.g. the largest .jpg files). I'm running Pop!_OS and I'm assuming there's some way to do this in the terminal, or alternately some utility I could use.
More Specific Details
I'm cleaning up my digital music library, and I realized in setting it up I made some errors by saving some very high res cover art. Many of my Bandcamp purchases come with a
cover.jpg
orcover.png
file that is several megabytes large. I made the mistake of writing these into the files (adding, for some albums, an extra, say, 100 MB across all tracks). They also take a lot longer to load when I pull them up in my cloud music player. I'd like to be able to identify the albums with the largestcover.*
files so that I can go in and replace the album art with a lower res version and gain back all that wasted space lost to unnecessary duplication.I could go folder by folder and take a look at the sizes of each, but I figure there's an easier way to surface the ones that need my attention. Everything I've looked at online so far has helped me figure out how to identify the biggest files in general, but all that will do is surface the actual audio files, when it's the cover art that needs the specific attention.
Also, in case it's necessary information, the directory structure is
Music/[artist]/[album]/cover.*
Any help will be very appreciated!

Ubuntu sends http requests to Google cloud, here’s a fix

Ubuntu has this package installed by default:
network-manager-config-connectivity-ubuntuIt's only purpose is to provide settings for NetworkManager to send requests to connectivity-check.ubuntu.com , and based on the result (AFAIK) detect redirection by captive portals and open an ISP's page (think public WiFi, or hotel rooms, where you need to authorize to access the net).
Well, connectivity-check.ubuntu.com is hosted on Google cloud (you can check that by running:
dig connectivity-check.ubuntu.com whois [the IP from previous query]
), so by default Ubuntu sends requests to a Google cloud page.
I don't say Google counts daily active Ubuntu users (because many of those have the same IP), or that Google actively logs and analyzes that data. But some of you guys may not like that behavior.So what's the fix?
Purge the package
sudo apt purge network-manager-config-connectivity-ubuntu
If you do need a captive portal detection, create your own config file to query some HTTP (not HTTPS) page of your choice, in the example below I have a Debian page used for the same purpose. Use your favorite text editor to create and edit /etc/NetworkManager/conf.d/90-connectivity-custom.conf :
[connectivity] uri=http://network-test.debian.org/nm
Restart NetworkManager
sudo systemctl restart NetworkManager
If you run an Ubuntu derivative, please report if you have network-manager-config-connectivity-ubuntu installed in the comments.

Details on the phone itself (Both are the same, the USA refers to supply chain):
Libram 5 - $799
Libram 5 USA - $1999I think it's quite a tell about how much our electronics are subsidized by sourcing from inordinately cheap labor compared to the (mostly) German/USA labor for the USA phone.
PureOS itself looks like it could be a decent entrant to breaking the mobile duopoly. The only sticking point for me would be various applications that don't offer browser options (read: 2 factor authentication apps).

I am stuck on Windows 10 for the time being, and I wish to make it function similarly to the arrangement I have on Linux, using xcape and xmodmap. This is what I need:
- Caps sends Escape on tap and Control on hold
- Tab sends Tab on tap and Alt/Meta on hold
- Escape sends Caps (I rarely use this one).
I find this setup extremely comfortable. Is there a way to achieve this on Windows (that a layman like myself could do?).

Hi, hope this is the right place for this question. I'd like to learn Autodesk Fusion 360, but all of my devices are running either Ubuntu or ChromeOS. I've tried to get F360 running on my ubuntu desktop with both Wine and Lutris but I haven't had success. There is also a web application for F360 but it is feature limited.
It seems like the only way to get this program running is to use a virtual machine, but I don't have much experience in this area. Do I need to buy a windows license and set up my own VM or is there a service where I can rent time on a preconfigured VM somewhere?
Thanks for reading, hope to hear your suggestions.

Most recent update is here.
The Tildes community has been amazing and patient with me as a new and uninformed Linux user, and I'm greatly appreciative of that. I return to you today with yet another request.
Hardware
System76 Oryx Pro
Distro: Pop!_OS 19.10
Issue #1 (mission critical)
Brother MFC-L2750DW
I have a Brother printer/scanner for which I have installed the drivers using the .deb file provided on the Brother site. It's connected via USB. Printing works fine; scanning does not. My husband and I both need the ability to scan for our jobs, so this issue is pretty important to us.
I am using the program Document Scanner (I believe it's one of the GNOME default programs?). When I open the program it says "Searching for Scanners" and then recognizes my scanner, giving the model number and says it's "Ready to Scan". Whenever I attempt to scan, however, whether from the ADF or the flatbed, it says "Unable to connect to scanner". I am not sure how to proceed, and any guidance on this would be greatly appreciated!
Issue #2 (optional)
Hyperkin Duke Wired Xbox Controller
This is an optional issue and not at all one that needs to be solved by any means. A while back my husband got me this because it's my absolute favorite controller of all time (I know, scoff all you want!). It worked fine in Windows, but now that I've shifted over to Linux it has been sitting and gathering dust.
When I plug it in the controller rumbles briefly (which it also did on Windows), but other than that does nothing. No input is accepted. If it's easy to get this up and running in Linux, I'd love to be able to use it, but if it's not that's totally fine. I have another controller I can use, and again, none of this is essential to my work. I just figured since I was asking for help I'd throw this in here too.
If you need any additional information or need me to try any specific things, let me know!
