Not changing UI

au flag

In 21.04, the UI should be displayed like this (image from wikipedia):

Ubuntu 21.04 with Gnome desktop

But, it displays like this in my computer:

Ubuntu 21.04 with Unity desktop

I upgraded 16.04 to 18.04, then 18.04 to 20.04, then 20.04 to 21.04. How can I fix this UI?

What is wrong with the UI and who said wiki is correct?

I’m confuzzled. Is the concern the lack of desktop icons? You may be able to have them enabled by toggling some of the display settings

I don't see the problem, please update your question and explain.

The problem is that you upgraded from 16.04 to 21.04 which is not a supported upgrade path.

In 16.04, Unity was the default Desktop environment. As you used an unsupported upgrade path from 16.04 -> 21.04 it was not changed after your upgrade. So, you're still using unity-desktop as default.

Install ubuntu-desktop if not already installed and switch the Desktop Environment to Gnome before you login.

sudo apt install ubuntu-desktop

You probably also need to change your Display manager to gdm3 (Default in 16.04 was lightdm). Run sudo dpkg-reconfigure gdm3 and chose gdm3.


However... I guess, you will notice more issues related to using an unsupported upgrade path. If that is the case, you should consider a reinstall.

I upgraded it by 16.04 to 18.04 to 20.04 to 21.04. It took about 1 days!

There is no tested, supported upgrade path directly from 20.04 to 21.04. That suggests you used an *unsupported* method. In turn, that suggests you may have used unsupported methods for other steps of your upgrades. We don't know what you did wrong -- there are too many possible variables. I can tell you that test installs that I have *properly* release-upgraded from 16.04 to 18.04 correctly switched from Unity to Gnome.

No I mean I upgraded 16.04 to 18.04 then 18.04 to 20.04 then 20.04 to 21.04. But I accidently removed GNOME a while ago and I will install 16.04 and upgrade to 18.04

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
