Because linux kernel 1 is being updated, the old kernel is no longer in use after the update, but the old kernel files are still in boot, occupying space. After several updates, the boot partition will be full, indicating that boot disk space is insufficient.

The solution

Delete unused kernel files to free up space.

Complete the following steps

1. View the installed kernel dpkg --get-selections |grep linux-image

eason@eason:~$ dpkg --get-selections |grep linux-image
linux-image-4.4.0-21-generic deinstall
linux-image-4.4.0-57-generic install
linux-image-4.4.0-59-generic install
linux-image-4.4.0-62-generic install
linux-image-4.4.0-64-generic install
linux-image-extra-4.4.0-21-generic deinstall
linux-image-extra-4.4.0-57-generic install
linux-image-extra-4.4.0-59-generic install
linux-image-extra-4.4.0-62-generic install
linux-image-extra-4.4.0-64-generic install
linux-image-extra-virtual install
linux-image-generic install

followed deinstall Is the deleted kernel and can be ignored

2. Use uname -a See which kernel you are currently starting

eason@eason:~$ uname -a
Linux eason 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

The output shows that the kernel we are currently booting is 4.4.0-62-generic

3. Run apt-get remove The uninstall command unloads the other kernels, and to be on the safe side, keep the last two versions of 1.

sudo apt-get remove linux-image-4.4.0-57-generic
sudo apt-get remove linux-image-4.4.0-59-generic
sudo apt-get remove linux-image-extra-4.4.0-57-generic
sudo apt-get remove linux-image-extra-4.4.0-59-generic

If the prompt has not uninstalled clean can be executed sudo apt-get remove To uninstall.
