On starting OS and when I try to update and install stuff I get the error boot partition low space

I've been having lots of issues with freya so I'd like to get stuff running smoothly.

Partition scheme I have

boot: around 300Mb root: around 30/35Gb Home: more than 100Gb Swap: 10Gb (around 1.5 my RAM)

As advised in lots of guides

Boot partition is full. Why are kernel files pilling up in the partition? Shouldn't they swap when upgrading? Will this always happen once in a while? What files to delete? PlayOnLinux added lots of crap on terminal when I tried to use another question solution

It seems you have more unused kernels:(Open terminal and run the commands)

(I suggest boot to latest kernel)


Remove Manually:

First list current kernel:

uname -r

Example output:3.19.0-28-generic

To list all kernels :

dpkg --list | grep linux-image

Now purge old kernels manually,(be sure don't purge current kernel)

sudo apt-get purge linux-image-3.16.0-34 linux-image-3.16.0-46 linux-image-3.16.0-48 linux-image-3.16.0-49 

Note: In general to remove old kernels use linux-image-x.x.x-x where replace x with numbers.


Automatic:

sudo apt-get purge $(dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve "$(uname -r | sed -r 's/-[a-z]+//')")

Note: you can verify deleting kernels with following command-here the output excludes current loaded/running kernel .So please boot to latest kernel.

kernelver=$(uname -r | sed -r 's/-[a-z]+//')
dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve $kernelver
