I've been running my head into this wall for about a week now, any help would be appreciated. I'm trying to rescue this old ubuntu machine that I have, but I'm not making much progress. Let me fill you in on what I've tried.
Years ago I had tried wiping the OS by installing Fedora from an ISO that I put on a CD, but I didn't know what I was doing and somehow managed to get the computer into a state where it was saying that there was no OS when I went to boot up the machine. Recently I came back to my computer in this state. I tried to continue with the Fedora installation but apparently I still don't know what I'm doing and couldn't complete the installation correctly. But when I tried rebooting to the hard drive, the computer booted up my old Ubuntu OS which I thought was gone. I was able to sign in and take the files I wanted off the machine before I messed with things any more because at this point I don't care if I'm starting from a blank slate. I tried using the Update Manager to fix things but the first thing I see when I opened it is this:
"Your Ubuntu release is not supported anymore" - "You will not get any further security fixes or critical updates. Please Upgrade to a later version of Ubuntu Linux." with the option "Close".
When I click "close" it then shows this:
![Not all updates can be installed](https://i.stack.imgur.com/FsQPk.png)
![could not download the upgrades](https://i.stack.imgur.com/fXpKo.png)
and when you scroll to the right it says:
![404 not found](https://i.stack.imgur.com/blG2h.png)
I'm guessing this has something to do with the whole "release is not supported" issue, but I don't know what to do. In the Update Manager, I see that there's a section that says "New Ubuntu release '14.04.6 LTS' is available" and when I click "Upgrade", it looks like it downloads two packages real quick before doing... nothing. When I try going online it says:
"Secure Connection Failed" - "An error occurred during a connection to mail.google.com. Cannot communicate securely with peer: no common encryption algorithm(s). (Error code: ssl_error_no_cypher_overlap)"
whenever I try accessing a site with HTTPS. I know these are some separate issues. I'm just painting a picture here about the state of things.
I had enough of all of this and decided to install lubuntu-18.04.5-desktop-i386 from a USB memory stick. I used rufus-3.16.exe on my Windows machine to setup the ISO on the USB stick. Here's my Rufus settings:

Now, maybe this next detail is the issue, but I don't suspect that it is. Apparently I have no USB sticks that are large enough to contain the ISO file. So I found a micro SD card that's large enough. I had to put the micro SD card into a micro SD to SD card adapter, and then put that into a SD card to USB adapter. Then I was able to get Rufus to setup the USB stick correctly. I got the Ubuntu machine to see the USB stick and it shows the lubuntu install screen. When I try to install it, I get kernel panic messages such as these:

I tried updating Initramfs on my machine before attempting this again and it seemed like it attempted to update. I'm not sure that it did.
Today I found my way to this menu:
![repair broken packages](https://i.stack.imgur.com/KWo1X.jpg)
and attempted to "repair broken packages" and saw this mess:
![failed to update](https://i.stack.imgur.com/FGcqJ.jpg)
which looks a lot like what the Update Manager was doing so I think I'm just running in circles at this point. Here's some info from my Disk Utility:

You can see the hard drive, it's partitions, a USB stick that I used to get the screenshots from the Ubuntu machine to my Windows machine, and the 10+ yr old Fedora CD.

I hope this is enough information to help with at least what my next steps should be.
