I'm getting an error that my disk if full. Please see image and if anyone could help me understand why or how to clean up the area that is 96% full, I'd appreciate it. thanks..
I would first check the lost+found folder within the boot folder. Normally that folder is empty. You could use WinSCP for to do the check and to see what all is inside of lost+found, then could copy to your PC and/or delete to free up space. WinSCP is freeware and use SSH with the same credentials as PuTTY.
Probably you have a lot of unused kernels. Please show us the output of the following command: Code: ls -la /boot
