I'm not sure if this is the right category, but I would like to know how to, either, upgrade or install to Linux Kernel 5.10 ?
Just update system normally. You can do
sudo pacman -S linux-zen or linux-tkg-bmq ( whichever is there you can check by typing neofetch)
Delay this update if you want to use virtualbox( it will receive support in a few days or weeks). If you don't use virtualbox then you can update.
neofetch or uname -r in your terminal.
Thanx, for everybody's help. I figured it out. I don't use virtualbox.
Thanx. I figured it out right after I posted my question. I don't use virtualbox. Thanx again & Have a great Christmas !
