Solved Manjaro and virtualbox glitch

[Danbor]

Hello all. This problem isn't vital but I would like to solve it. I'm running Virtualbox 7.2.8 and the host id running Mint 22.3
I've been trying to get guest editions installed on a Manjaro virtual machine, and I've encountered an error I can't seem to overcome. When I run the guest editions installer, it tells me that
"Kernel headers not found for target kernel
6.18.26-1-MANJARO. Please install them and execute
/sbin/rcvboxadd setup".
Can anyone tell me how to fix this?
Below is the output from the run command.

❯ sudo sh ./VBoxLinuxAdditions.run

Just like the output tells you:

sudo pacman -S linux-headers
/sbin/rcvboxadd setup

Just like the output tells you:

sudo pacman -S linux-headers
/sbin/rcvboxadd setup

Ok, tried that, here is the result ...
sudo pacman -S linux-headers /sbin/rcvboxadd setupcd ..

Please don't copy these commands all at once, if you pay attention to output you can see why it doesn't work.
Run each line separately...

Option 1:

sudo pacman -Syu linux618-headers
/sbin/rcvboxadd setup

Option 2 (IF option 1 doesn't work):

sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')
/sbin/rcvboxadd setup

Thanks for the help! Much appreciated!
Though neither option fixed the issue, they did direct my investigative direction. Ultimately, I used
sudo pacman -S --needed base-devel, reran /sbin/rcvboxadd setup and rebooted.
Working fine now! And, I added to my limited knowledge.
