I tried to place an install it link into an answer, but apps.ubuntu.com went away and stopped working, it redirects to the Snapcraft store now.
The image was there all right but the link was redirected to https://snapcraft.io/store -- this isn't really what we want.
What happened to apps.ubuntu.com? Is there a new place where Ubuntu software can be found?
Unfortunately, Ubuntu Software Center was discontinued in 2015. It was replaced with GNOME Software (rebranded as Ubuntu Software) - so unfortunately the old links to apps.ubuntu.com do not work anymore . The new standard for software from an app-store like interface under Ubuntu is "snaps" from snapcraft and not deb packages any more - that's why you get redirected.
