Bug Description

When running the installer from a live session of Ubuntu GNOME I experience the issue shown in the attached screenshot when using a dark theme.

On the panels that show users whether they

1) have enough disk space available,
2) are plugged into a power source (when on a laptop),
3) are connected to the internet,

the background colour seems to be hard coded to white. This doesn't work when the theme is dark, because the text on the panels turns light also in line with the dark theme, rendering it undreadable.

The possible solutions could be

1) hard code the text colour to remain black instead of following the theme, or
2) code the background colour to follow the theme.

I thought default theme of Ubuntu GNOME works fine. What is "a dark
theme"? How do I set it and/or which packages does it come from?

Default theme is Ubuntu GNOME works fine. A dark theme is one that makes window borders and menus dark. In Ubuntu GNOME you can make the default Adwaita theme dark in the Tweak Tool under Appearance, where you switch Global Dark Theme to ON (this is the first option under the Appearance tab, and by default it is switched OFF).

This is also a problem in KDE Plasma 5 when Breeze Dark Theme is active. See
