I have not enough experience to know if the following steps I think I have to do to update the kernel of my Elementary upto 4.15 are correct. Can somebody check it and tell me and tell me if it will work 100%: 1.- Create a directory specifictally to do this operation. For example /inux415 2. - cd /linux415 3.- Download as follow (for 64 bits of course: -http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2018-01-29/linux-headers- 4.15.0-999_4.15.0-999.201801282100_all.deb - http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2018-01-29/linux-headers-4.15.0-999-generic_4.15.0-999.201801282100_amd64.deb - http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2018-01-29/linux-image-4.15.0-999-generic_4.15.0-999.201801282100_amd64.deb 4- Install all: sudo dpkg - i *.deb 5.- Reboot. I hope that somebody will help me. Thanks and blessings.
If, I'm not mistaken, you should update your GRUB after installing the new kernel. Also, you can try Ukuu, an utility to perform kernel update
