Stuck on "update-initramfs" during upboard kernel installation

I am trying to install Ubuntu Mate 18.04.5 on my Up squared board. After the installation is done and the system is rebooted using "nomodeset", I follow steps 1 and 2 of the installation guide:
1. After the reboot you need to add our repository:
sudo add-apt-repository ppa:up-division/5.4-upboard

  1. Update the repository list:
    sudo apt update

Then I try to install the kernel:
Install our kernel(18.04 and 20.04 share the same 5.4 kernel):

sudo apt-get install linux-generic-hwe-18.04-5.4-upboard

During the installation, the prompt hangs at:
update-initramfs: Generating /boot/initrd.img-5.4.0-1-generic
possible missing firmware /lib/firmware/rtl_nicrtl8125a-3.fw for module r816

The installation does not complete. I have tried almost everything to solve this issue. Does anyone have any suggestions?
