Build failing

[Matt1700]

I'm trying to update the kernel of android x86 8.1 r5 to version 5.8 because versions older than 5.2 contain kernel drivers that are not compatible with the Intel AX201 wireless adapter.

After issuing the commands:

mkdir android-x86
cd android-x86
repo init -u git://git.osdn.net/gitroot/android-x86/manifest -b oreo-x86 -m android-x86-8.1-r5.xml
repo sync --no-tags --no-clone-bundle
cd kernel
git remote add maurossi https://github.com/maurossi/linux
git fetch maurossi kernel-5.8_si_next
git checkout FETCH_HEAD
cd ../external
rm -rf kernel-drivers/
git clone -b kernel-5.8 https://github.com/maurossi/kernel-drivers.git kernel-drivers
cd ..
. build/envsetup.sh
lunch android_x86_64-userdebug
m -j3 iso_img

I get the following error:

Am I doing something wrong?

Solved, just needed to install libssl-dev

sudo apt-get install aptitude
sudo aptitude install libssl-dev
