I installed Ubuntu 18.04 but wifi adapter doesn't work. It works on Windows (dual boot) and the Ethernet/wired connection works just no wifi and potentially Bluetooth.

I tried these lines:

sudo apt update

sudo apt install build-essential git dkms

git clone https://github.com/tomaspinho/rtl8821ce.git

cd rtl8821ce

sudo ./dkms-install.sh

sudo modprobe 8821ce

But I don't think that's the right driver, so I went onto https://github.com/samcv/A485-RTL8822BE-firmware and just got errors.

Does anyone know a simple fix I can use please? I'm kind of new to Linux. Any help will be much appreciated.

Be certain that Secure Boot is disabled in your BIOS, otherwise no software modifications will have effect.

To get better info about that "UNCLAIMED" network controller, update your Ubuntu with the...
sudo update-pciids
...command, then repeat the...
sudo lshw -class network
...command. Your rig should then identify the RTL8822BE 802.11a/b/g/n/ac WiFi adapter.

You might as well also do the...
sudo update-usbids
...command, for possibly updated info on your various USB devices.

I'm not familiar with Manjaro Linux, but I'd guess that boot boohoo is related to EFI-privilege or a lack thereof.
