= Removing old Kernels =

Install Synaptic package manager:

<syntaxhighlight lang=bash>
sudo apt-get install synaptic
</syntaxhighlight>

Show your current kernel, this is the one you need to keep at minimum:

<syntaxhighlight lang=bash>
uname -r
</syntaxhighlight>

<blockquote>
<syntaxhighlight lang=bash>
linux-image-3.13.0-125-generic
</syntaxhighlight>
</blockquote>

Remove older kernels:
# Start synaptic.
# Search for 'linux-image'
# Filter for installed packages
# (multi) select the packages with names like 'linux-image-3.13.0-125-generic'. Do  '''NOT''' select your current or newer kernels. You might want to keep one older version as well.
# Right-click a kernel and choose 'Complete removal'. Related packages will be selected automatically.
# Click the Apply button. It might take some time to complete

Remove corresponding headers:
* Repeat this search and complete removal for 'linux-headers' with names like 'linux-headers-3.13.0-125'. Again, do  '''NOT''' select your current or newer kernels.
