I completely broke Kubuntu

So like I was trying to install Davinci resolve (an editing program) and while doing so it basically said "removing" followed by that appears to be everything installed on my computer

So I nope right out of there and I notice a bunch of important things are missing ex: the terminal, file manager, etc

So I just decided Maybe if I reboot everything will be a ok

And now on this screen and it won't even let me enter my logic

This was the latest update of Kubuntu And idk what I did wrong or how I got here

I've only been using Kubuntu for probably about 4 months ish

Edit: please help

Edit 2: I got it working by reinstalling Kubuntu as suggested, Thank you for the help :>

Possibly this contains the reason why it broke:

I don't know how you went about installing davinci, but if you added a repo or ppa that is incompatible with the version you had, apt would try to resolve it by removing everything incompatible.

Easiest way to fix it would be to reinstall Kubuntu and all the packages you had, while keeping your old home partition/folder. That way all your data, downloads and most of the configs will stay.

The installer used to have a checkbox for that somewhere, at least back in the day when I used Kubuntu. Afaik it would automatically detect that a home already exists, even if it is not on a seperate partition.

But just to be extra safe, I'd recommend just live booting some other OS and backing up your home to an external drive.
- It's really late for me right now but I'll talk so my brother tomorrow about borrowing an extra hard drive and attempting this then
  
  I fixed it It's finally working It took me longer then I'm willing to admit but There's no reinstall button in the installer
  
  But to do it is to select manual partition and simply set the original partition as /
  
  Amazingly everything is exactly how I left it I expected to have to reconfigure my settings n such but it managed to retain my previous configurations
Edit: please help

Best edit ever
You can go to /var/log/apt/ and read the history.log as it will contain every single package that you did install/remove.

Based on that you can just restore it to working state by manually undoing the changes (removing installed, installing removed)
Permanently Deleted
- I'm lucky enough to have other systems around to back up the drive with for the reinstall
  
  I am absolutely going to fiqure out how it set up timeshift now
ctrl+alt+f1 get to tty and install back those uninstalled?
- If apt suggested to uninstall these, there is a problem that may just occur again
The top answer here worked for me a long (~10 years) time ago, it might still work. Backup your home folder with a livecd before trying anything though.

Lol

Please install Davinci Resolve in a Podman/Docker container.

https://github.com/zelikos/davincibox

install podman and distrobox

clone the git repo

place the davinci binary in there

run setup.sh

And this looks like just sddm-breeze is missing
- Will absolutely do
There is not enough information in your post to help you. Here's a preliminary list of questions that need an answer before anyone can give you a meaningful contribution.

Where did you get "Davinci resolve" from?

What instructions were you following to install it?

Did the installation finish?

Have you attempted to login using a text console?

Which version of Kubuntu were you using and which version of "Davinci resolve" were you attempting to install.

  2, it was a basic installer except it was angry about some dependencies, specifically I installed libasound2 I believe and it started removing stuff
  
  3, Nope
  
  4, I'm not sure how
  
  5, what ever the latest is
  
  6, again what ever the latest is

  I hope you've now understood why -on Linux- you should never try to install stuff like how you were used to on Windows. Unless, you 100% know what you're doing.
  
  Seems DaVinci Resolve does not have support for the latest Ubuntu's yet.

  For number 4 since it is very useful in such situations: press Ctrl + Alt + one of the F keys (usually one of 3,4,5) And to go back it is usually one of 1,2,7,8
  
  It saved my ass many times.
At login, press ctrl-alt-f4 or f5 or one of the F* keys until you get a text based login screen. (Might need to press enter on a blank screen for the login to appear)

Login as your user and password.

Sudo apt install kubuntu-desktop
On your next OS reinstall, perhaps consider using an atomic distro. They’re WAY harder to break in this fashion - primarily because you can just roll them back to the previous known-good state.

Edit: genuinely curious what the downvotes are for - I thought atomics were quite popular here?
What guide did you follow to install Davinci?

It probably contained something that removes a lot of stuff. Like replacing a dependency with a davinvi specific one, which uninstalled most of the system.
If you can intercept boot ( press a key to get to the grub menu or whatever... I haven't used Ubuntu in a while so maybe it's not so simple anymore) you may be able to enter rescue / single-user mode and let apt complete the changes and then revert them.

A clean reinstall may be easier depending on how much you've changed on the system. Easier isn't always better, fix this and you'll know how to do it again in the future.

Easiest fix:

1.- Download Fedora

2.- Install Fedora

3.- Never look back

4.- Be happy the rest of your life
- Typical solution for you. Change distro.
  
  Exactly. At least for me, Fedora has been flawless since version 36.
