I'm new on elementary OS and Linux. I've to update the software (using the software update application) but when I click "update now" I've got a message that says: clean the trash and use "sudo apt-get clean". I did it but it doesn't work anyway.

Can someone help me? What I have to do? (sorry for the bad english)

edit (1): running df -h I have:

File system     Dim. Usati Dispon. Uso% Montato su
udev            3,4G  4,0K    3,4G   1% /dev

/dev/sda1       511M  3,4M    508M   1% /boot/efi

edit (2): using Gparted I have this. enter image description here

and I can't resize the partition

  • When you run df -h, how much space is available on your hard drives? (You can paste the result into your question, if it would help.)

Your /boot partition will be locked in gparted while your operating system is running (as the partition is mounted and in use). Instead, boot into a "live CD" (or drive) to modify the partition while the operating system is not in use.

You'll want at least twice as much space in your boot partition (~500 MB), and you could probably size down that EFI partition (Ubuntu recommends 100-250 MB instead of your 512 MB). And this should go without saying, but remember to backup any important data before proceeding in case you mess up your drive.


You haven't allocated enough space for your boot partition (where the kernel goes).

Boot into a live session with the elementary installer, and then follow this tutorial to shrink your root partition to free up some room, and then resize the boot partition so it is around 500MB.

  • thanks! When I installed the OS I haven't touched the default settings, I hope it will work!

  • Gparted doesn't work. I installed it using the terminal and I can see the partitions of my disk. But when I select the /boot I can't use "resize" because it's disabled!

  • Ah, this will be because it is currently mounted. If you still have the USB flash drive with the elementary installer then I believe that has GParted installed. Boot from that and try again.
