Bila anda menggunakan VirtualBox 6.1.16 atau lebih rendah, ketika menggunakan kernel 5.10 akan muncul pesan error
bila perintah yang diminta dijalankan
sudo /sbin/vboxconfig
di log build (/var/log/vbox-setup.log) kernel module Virtualbox muncul error

Solusi VirtualBox untuk Kernel 5.10
Solusinya adalah menggunakan VirtualBox 6.1.18 yang bisa di download dari virtualbox.org
Disini saya menggunakan Fedora 32, caranya sama untuk Debian atau Ubuntu tinggal disesuaikan nama file yang di download
Download VirtualBox dan Extension Pack
wget https://download.virtualbox.org/virtualbox/6.1.18/VirtualBox-6.1-6.1.18_142142_fedora32-1.x86_64.rpm wget https://download.virtualbox.org/virtualbox/6.1.18/Oracle_VM_VirtualBox_Extension_Pack-6.1.18.vbox-extpack
Install VirtualBox dengan
sudo dnf install ./VirtualBox-6.1-6.1.18_142142_fedora32-1.x86_64.rpm # ubuntu/debian ganti jadi sudo apt install ./VirtualBox-6.1-6.1.18_142142_fedora32-1.x86_64.rpm
Install VirtualBox Extention Pack
echo y | sudo vboxmanage extpack install Oracle_VM_VirtualBox_Extension_Pack-6.1.18.vbox-extpack --accept-license=yes
setelah selesai VirtualBox bisa digunakan kembali.
