How can I install Pantheon desktop environment(stable) on Ubuntu 20.04? Everything I found on the internet was for old version or not working(people said in the comments).
I am getting dependency error while installing pantheon-files
$ sudo apt install pantheon-files

I am trying to build the pantheon elementary greeter on Ubuntu but it keeps failing at the build stage since it can't find accountsservice. But accountsservice is clearly installed.. I am following the build instructions given on the page.

The strangest part is that accountsservice is already installed to its latest version.

What is going on ? Why can't meson find accountsservice when it is clearly present ?
I'm running Ubuntu 18.04.3 with pantheon desktop, I installed the Nvidia drivers with the following command:
$ sudo apt install nvidia-driver-440
After the process was completed I restarted my pc. Now the NVIDIA X Servers Settings are installed and the app center shows the driver was successfully installed, but when I try to change the main GPU with prime settings, it doesn't work. Prime settings Additional drivers settings
I ran the following command to figure out what GPU is really working. This is what I get:
$ glxinfo|egrep "OpenGL vendor|OpenGL renderer"
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) UHD Graphics 620 (Kabylake GT2)
I don't know if I have followed any wrong procedure. Thanks for your help!

GPU: Intel Corporation UHD Graphics 620 (rev 07) NVIDIA Corporation GM108M [GeForce MX130] (rev a2)
Edit: This is what I get from running the following command.
$ lspci -k | grep -EA3 'VGA|3D|Display'

I'd like to have Pantheon as another session option, next to GNOME and Ubuntu's GNOME variant.
Is there a way I could install Pantheon on Ubuntu 19.04 without messing up various parts of my system? (E.g. the theme changing, maximize and close window buttons changing placement, etc.)
(I would like a full-fledged system, not a system running in a VM)
