Removing old Kernels
Install Synaptic package manager:
sudo apt-get install synaptic
Show your current kernel, this is the one you need to keep at minimum:
uname -r
linux-image-3.13.0-125-generic
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.
