I tried everything I could find in the following links:
How can I enable Compose key?
https://help.ubuntu.com/community/ComposeKey
https://wiki.ubuntu.com/ComposeKey

However, I still could not get the compose key working on my freshly installed Ubuntu 20.04.

I use the english (US) keyboard layout, but I need to be able to type Umlauts with the compose key. In Ubuntu 18.04 and 16.04 it worked just fine and I mapped set and used the super key without any problems.

In 20.04 I tried different keys but none of them worked.

The output from gsettings get org.gnome.desktop.input-sources is:
xkb-options ['compose:rwin', 'eurosign:e', 'esperanto:qwerty'], however sudo vim /etc/dconf/db/local.d/00-input-sources contains compose:ralt...

Gunnar's comment pointed me into the right direction.

gsettings get org.gnome.desktop.input-sources shows the current active settings and therefore I was able to find out that I used the wrong key.

Using the gnome-tweak-tools I could update the settings accordingly to the right-ctrl which finally worked.

Thanks to the previous answers, here is the method that worked for me:

List keyboard settings:

gsettings list-recursively org.gnome.desktop.input-sources

Set the compose key:

gsettings set org.gnome.desktop.input-sources xkb-options "['compose:paus']"

List possible values for compose key:

grep "compose:" /usr/share/X11/xkb/rules/base.lst

If you prefer to use the command line, see this answer. Worked like a charm for me on U20.04.

If you prefer to use the GUI, and don't mind installing a package just for defining the compose key, see this answer.
