ROS Melodic Install dkms error in Ubuntu 18.04 - Error! Bad return status for module build on kernel: 5.4.0-89-generic (x86_64) - ubuntu-18.04

Question

I was trying to install ROS Melodic, and got this error:-
(ROSMelodic) (system) t#tsd:~/git/ROSMelodic$ sudo apt install ros-melodic-desktop-full
Reading package lists... Done
Building dependency tree
Reading state information... Done
ros-melodic-desktop-full is already the newest version (1.4.1-0bionic.20211216.192238).
The following packages were automatically installed and are no longer required:
golang-docker-credential-helpers gyp libjs-async libjs-inherits <etc. etc. long list of installed packages...>
Use 'sudo apt autoremove' to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 87 not to upgrade.
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n] Y

sudo apt install darling-dkms
E: Unable to locate package darling-dkms

Answer 1

The first problem probably made all the other errors message to appear, probably check darling-dkms.
sudo apt remove darling-dkms # remove faulty package
sudo apt update && sudo apt upgrade # update & upgrade packages. This should also upgrade your kernel to a newer version (for me, this was 5.10.0-1051-oem)
sudo apt install darling-dkms
Which one do you have installed and what is the required version?
Also, did you check installation guide:
http://wiki.ros.org/melodic/Installation/Ubuntu
There are some pre-installation steps:
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
And:
sudo apt install curl # if you haven't already installed curl
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

Answer 2

Downloading and installing the Debian of darling from this website
https://github.com/darlinghq/darling/releases
https://github.com/darlinghq/darling/releases/download/v0.1.20210224/darling-dkms_0.1.20210224.testing_amd64.deb
solved this darling-dkms error
From following the instructions in the ROS website, I also had to do this
sudo pip install rosdep==0.21.0
