partitioning - Boot Partition Full



When I run Software Updater, it says that I don't have enough free disk space. I need 29.3 Mb of free disk space on '/boot'. I've tried the solution at How do I free up more space in /boot?. It removed a lot, but I need more. I am running the newest version of Ubuntu Studio. Here's some data:

Thanks Guys, I've been at this for a while, kinda stressed.



So after cleaning, we can see you have two different kernels left: generic and lowlatency.



The uname command shows that you are using the lowlatency. If you are not using the generic kernel, you could delete its related files by running :



sudo find /boot -name "*generic*" -delete


This should halves the space used in /boot.




You could/should also grow your /boot partition by using gparted in a live-CD session for example, but you will probably have to shrink adjacent partition.
