I tried to upgrade from 19.10 to 20.04 and it crashed my system. and I don't know what to do.

Asked by WLB on 2020-07-18

When I clicked on the system upgrade, it stated that 19.10 (not sure of exact no., but definitely 19) was no longer supported and that I had to upgrade to 20.04. I clicked to upgrade and it got all the way to installing the new packages and then a messages saying "oops, there was an error" popped up and my screen went black. I restarted my computer and nothing. Everything is gone. I have absolutely no idea as to what to do. I am on my backup Mac laptop and I desperate need my desktop. What do I do? Please help!

There is nothing on the screen. It won't reboot.

Do you see the logo of your computer's manufacturer on the screen when you switch on the computer, or some "press f12 for BIOS setup" text?

What make and model is the system?

WLB (wlbates) said : #4

Yes I do. I am in the main screen.

... the main screen of what?

My system was custom built. Ubuntu was the only operating system ever
installed on it.

I am trying to download the installation onto my Mac and then onto a disc
to try and reload it that way, but once it downloaded, I can't seem to get
the download copied onto a disc.

If you want to burn the Ubuntu installer to a disc on a Mac, then use the instructions in

https://ubuntu.com/tutorials/tutorial-burn-a-dvd-on-macos

WLB (wlbates) said : #12

I did try that and it would not work. I will try it again.

Hello again,

I was able to burn the CD and when I tried to install, I got the same message as before: end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block

Now what do I do?

Manfred Hampl (m-hampl) said : #15

Try selecting "try Ubuntu without installing" and perform a file system check on the rott partition on the hard disk.

WLB (wlbates) said : #16

Not sure I understand some of that, but I will try.

In a very early moment of booting you should see something like "press F12 for BIOS setup or F10 for boot device selection" on your screen (exact text depending on the BIOS manufacturer). You have to press the appropriate key to select that the computer boots from the DVD and not from the primary hard disk.

WLB (wlbates) said : #19

Good morning,

Thank you for hanging in there with me, and I appreciate your patience.

I got to the menu, but I have no clue as to which one to use.

Replying to the automated email and attaching an image doesn’t work. You’ll need to use a hosting service to make a url which you can then post as an update

WLB (wlbates) said : #21

OK, I stepped a little out of my comfort zone and was able to boot from the
CDrom. There was an indication that 20.04 LTS was already installed and I
had to allow a complete installation next to the previously installed
version. It was clear that the other installation was not complete.
Hopefully a bug was created to try and figure out why I got an error
message and completely crashed during a supposedly routine upgrade.

Thank you for your assistance, and hopefully I won't have any more issues.

Enjoy the rest of your weekend.
