For all releases of Ubuntu 18.04 and newer:
sudo snap install signal-desktop
- The snap is provided by the all-volunteer Snapcrafters team, a group of experienced and trusted experts from the Ubuntu Community who have been providing safe and secure snap packaging and regular updates for their adopted applications since 2017. The upstream Signal project does not provide a Snap package.

13@mubasshir00 concerning your credits: actually, these instructions can also be found (identically) on Signal download page behind the link Signal for Linux - Debian-based distros (bottom right).– ojdoJan 12, 2021 at 10:14

@Eric What errors did you get, at what point in the process? Help us fix it.– nealmcbJul 3, 2023 at 20:18
Apart from a deb package from the Signal PPA and snap package (sudo snap install signal-desktop), you can install it as flatpak (Follow the setup guide before installing):
sudo apt install flatpak
flatpak install flathub org.signal.Signal
Once installed, you can run it from the menu or use the following command in the terminal:
flatpak run org.signal.Signal
If you don't have/want to enable/d the Flathub repository:
flatpak install https://dl.flathub.org/repo/appstream/org.signal.Signal.flatpakref
Source: How to Install Signal on Ubuntu & Other Linux Distributions
Conveniently from the Ubuntu Software App (see below) as a snap package (no terminal command needed).
Once opened, type the Signal Desktop keyword in the search bar. Click on the Signal Desktop option available.
Now, click on the Install button available under the Signal Desktop to begin the installation.
For more details regarding the packaging, see comments of the other answer.
More details (e.g. how to remove it) and pictures, see Vitux page.
