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 tmpfs 691M 1,7M 690M 1% /run /dev/dm-1 910G 122G 742G 15% / none 4,0K 0 4,0K 0% /sys/fs/cgroup none 5,0M 4,0K 5,0M 1% /run/lock none 3,4G 156K 3,4G 1% /run/shm none 100M 48K 100M 1% /run/user /dev/sda2 237M 160M 65M 72% /boot /dev/sda1 511M 3,4M 508M 1% /boot/efi
and I can't resize the partition
