Budgie Installation?

Question

Does anyone know what happened to Budgie? I used the Gnome desktop when I first installed Ubuntu (about a year ago) but downloaded Budgie a few months ago and have been running it on both a desktop and a laptop.

Early this morning while I was working on the desktop I clicked on something that brought up a window saying that a complete installation of Budgie needed to be completed, and that the system would automatically reboot. I thought I'd already gone through this step on both systems, but went ahead and clicked on whatever... When the computer finished rebooting, Budgie was gone. Completely gone.

I've tried re-installing it from every Budgie app in the Ubuntu Software list, but it never installs. Then I noticed that every single Budgie app in the Ubuntu Software list shows an update of August 27, 2019. That's today's date (for me - it's just 7 a.m. where I am).

I'm running Ubuntu 19.04 and Gnome 3.32.1 on a Dell desktop, 64-bit Intel Core 2 Duo CPU E7500 @ 2.93GHz x 2. Sorry I don't know enough to volunteer whatever else might be helpful.

I really like Budgie and would like to get it back. If anyone can help, I'd appreciate it!

So, I tried the suggested command (sudo apt update && sudo apt upgrade sudo apt install ubuntu-budgie-desktop). This is the output:

It installed ubuntu-budgie-welcome. Let me log out and and see whether it shows up as an option for login...

No. Still just have a choice between Ubuntu / Ubuntu on Wayland / Unity.

I'm sorry to be sort of clueless about how some of this works. I do remember having to reboot during the initial installation. I thought I had done that step on both the desktop and the laptop, but when I was asked to do it again this morning I assumed that I must not have done it. (Sorry if I'm slight incoherent -I've been up all night.)

Actually, since I logged out and back in, the package that it installed (and I ran!) -- "ubuntu-budgie-welcome" -- is no longer to be found.

Either something is terribly wrong or I am really missing something. ;-/

I ran: apt policy budgie-desktop Output was:

budgie-desktop:

Update 8/28/19.
I came home early this morning (about 1:30 a.m.) and noticed that the update dates on all the Budgie apps have changed from 8/27/19 to 8/28/19. (one of them changed as I was checking them.) So I tried re-installing "ubuntu-budgie-welcome" and it seemed to work, until I ran the "Budgie Complete Installation" ...which brought up its window saying:

"Ubuntu Budgie Welcome is now a SNAP package. 
To complete the installation the budgie-welcome package 
 needs to be removed and the ubuntu-budgie-welcome snap package needs to be installed.  

 An automatic reboot will complete the installation.  

 Clicking Yes will complete the upgrade - continue?  

and after the reboot, Budgie had disappeared again.

Then I noticed a question/answer that I'd somehow skipped over before - the question "How to install Ubuntu Budgie over Ubuntu 18.04" and an answer posted by N0rbert last August. I tried what N0rbert suggested - installing the Budgie desktop as a task from a terminal with:

 sudo add-apt-repository universe  
 sudo apt-get update  
 sudo apt-get install ubuntu-budgie-desktop^  

and (lo and behold) I have Budgie up and running again.

My own programming days are many years behind me, and I'm new to Ubuntu (though I worked with Unix at Bell Labs 30 years ago). But I wonder if I have something tweaked on my system (since it's not exclusively Budgie) that kept the installation package I was trying to use from Ubuntu Software from running correctly -- but executing the apt-get commands directly through a terminal was able to force the installation to succeed...? or were those two things actually different in some way I don't understand? (e.g. an entirely Budgie version of Ubuntu vs. a simple desktop over Gnome-Ubuntu?)

Anyhow, I'm glad to be up and running again, though I've not yet had the courage to re-install "Budgie Complete Installation". :)

So, my final question (given this is the first question I've ever posted here):
Do I now close this question?
And if so, how do I do that?

Answer 1

I got Budgie running on my system again, thanks to an answer posted by N0rbert last August (in answer to the question "How to install Ubuntu Budgie over Ubuntu 18.04") by installing the Budgie desktop as a task from a terminal with:

  sudo add-apt-repository universe  
  sudo apt-get update  
  sudo apt-get install ubuntu-budgie-desktop^   

Budgie is running fine now, though I did not find any definitive answer to the question of why installing Budgie from the Ubuntu Software GUI did not work on my system.
