The appearance of various programs has changed to look old-fashioned

Question

Distributor ID: Ubuntu
Description:    Ubuntu 20.04.1 LTS
Release:        20.04
Codename:       focal

A member of the openshot team was helping me fix a problem and suddenly all the graphics went to Windows 3.1 He helped me to reinstall gnome but some issues haven't been fixed. Also, quite a few programs disappeared and I had to download them.

As seen below, the terminal appears 'old.' Before it was beautiful and purple. There was a hamburger menu in the right corner. Various icons now also look old fashioned, but some things are back to normal. Sorry that I don't have more info, I was just following his suggestions blindly and don't recall what happened exactly.

Have you gone through the application settings? What are the options under "view"? — Nmath, Dec 04 '20 at 22:03
From looking at the history, I suspect the problem is that you messed around with python, a critical system package. Fixing the result is beyond me. — Organic Marble, Dec 04 '20 at 22:08
@Nmath Thanks for that. Nothing under view or in the preference appearance settings fixed this — Cato Cross, Dec 04 '20 at 22:11
There's this `sudo apt-get remove python-is-python2 / sudo apt-get install python-is-python3` I don't have those packages on my 18.04 install but it sounds like it changed the system python version. See https://askubuntu.com/q/1296790/243321 — Organic Marble, Dec 04 '20 at 22:20
@OrganicMarble none of the standard apps use the symlink `python`, most likely the `python3` symlink changed. — not my real name, Dec 04 '20 at 23:17
@RayWu 'python-is-python3 is already the newest version (3.8.2-4)' But I notice that in my About section it says Gnome version is 3.36.3 — Cato Cross, Dec 06 '20 at 16:23
@CatoCross Are you sure that terminal is gnome-terminal? Type `xprop` and click on the terminal and show the results. — not my real name, Dec 06 '20 at 17:01
@RayWu Thanks! https://docs.google.com/document/d/16CYdIm4HqxJSTozMbgm1Z5tbQ8ZOZVmvq7gV-_qI6vA/edit?usp=sharing — Cato Cross, Dec 06 '20 at 17:36
@RayWu Terminal and about sections show different versions of Gnome installed. 3.36.3 and the other says 3.36.4 . Not sure if relevant. — Cato Cross, Dec 06 '20 at 17:38
@CatoCross AHA! This is *not* gnome-terminal, it's qterminal. Try typing alt-f2 and typing `gnome-terminal` — not my real name, Dec 06 '20 at 17:57
@RayWu Posted the solution above. Seems i have different DE installed. Do you think I should do a fresh install of ubuntu? — Cato Cross, Dec 06 '20 at 18:01
@CatoCross No, there is no need to do that. Just try uninstalling the package `kubuntu-desktop` and running `sudo apt autoremove`. And you are welcome to write that as an answer directly if you want, it's encouraged to help others with a similar problem. — not my real name, Dec 06 '20 at 18:02
@RayWu Thanks! When i boot up, in the gear icon for the login screen I have many options: LXqt / Ubuntu wayland / Gnome / Gnome desktop. Should i remove the others ones too? — Cato Cross, Dec 06 '20 at 18:18
@CatoCross Please remove the solution from your question, it clutters the text and is unnecessary. — not my real name, Dec 06 '20 at 19:26

The terminal is not GNOME Terminal at all. It looks like the terminal from the LXQt desktop environment.

sudo apt install gnome-terminal
sudo apt remove qterminal

I also see Discover, which is the app store from the KDE Plasma desktop environment. It looks like you mixed a bunch of DEs, which is not recommended, and you may want to remove it with

sudo apt remove plasma-discover

I think you likely also reinstalled the normal GNOME Software app, instead of the variation of it that Canonical created to support snaps.

sudo apt remove gnome-software
sudo snap install snap-store

You can also try these commands:

sudo apt remove kubuntu-desktop
sudo apt autoremove
