kernel upgrade in ubuntu 12

Question

I am using ubuntu 12.04.5 LTS server version. The kernel it has is Linux 3.13.0-32-generic x86_64.

I need to upgrade it to mainline 4.15 version.

I tried many times but i am unable to upgrade.

Upgrading from 3.13 to 4.1 is not a problem,it upgrades without any hassle.

When i try upgrading to anything over 4.1, i found it asks to solve kmod dependencies. I even installed kmod and its all dependencies form this site: Details of package kmod in trusty | Ubuntu. With this i still get error of dependency so i had to install module-init-tools to kmod from this site: Details of package module-init-tools in wheezy | Debian

and i did sudo update-grub

After this has been installed,it upgrades to 4.15 after reboot. Now i realized it has libc6 version 2.19 and i need to downgrade it else i get this error:

root@ubuntu:/usr/src# apt-get install byobu Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: byobu : Depends: python-newt (>= 0.52.2-11) but it is not going to be installed Depends: tmux (>= 1.5) but it is not going to be installed or screen but it is not going to be installed Recommends: screen but it is not going to be installed Recommends: tmux (>= 1.5) but it is not going to be installed libnih1 : PreDepends: libc6 (< 2.16) but 2.19-0ubuntu6.14 is to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). 

And again i have to downgrade this using this command:

sudo aptitude reinstall libc6 

After this i try reboot, i get back to kernel version 3.13 again.

Is it that ubuntu 12.05 can't be upgraded to mainline 4.15 or am i missing something here.

Thank you in advance. Expecting help here.

I tried really hard looking for all the available options in my test machine and could finally upgrade to 4.15 in ubntu 12.04.

This is what i did:

Download kernel 4.15.

Then download the following for solving the dependencies related to installing kernel 4.15:

wget http://ftp.us.debian.org/debian/pool/main/k/kmod/module-init-tools_9-3_all.deb wget http://ftp.us.debian.org/debian/pool/main/g/gcc-4.7/libgcc1_4.7.2-5_amd64.deb wget http://ftp.us.debian.org/debian/pool/main/g/gcc-4.7/gcc-4.7-base_4.7.2-5_amd64.deb wget http://ftp.us.debian.org/debian/pool/main/k/kmod/kmod_9-3_amd64.deb wget http://ftp.us.debian.org/debian/pool/main/k/kmod/libkmod2_9-3_amd64.deb wget http://ftp.us.debian.org/debian/pool/main/l/lsb/lsb-base_4.1+Debian8+deb7u1_all.deb 

After downloading, install the files using dpkg -i *.deb, and finally update-grub.

Reboot the server and check uname -msr.

Should work. Your kernel version is upgraded from 3.13 to 4.15
