Sometimes the update system will appear: W: mdadm: /etc/mdadm/mdadm.conf defines no arrays., W: mdadm: no arrays defined in configuration file. What should I do? Generally speaking, it is caused by insufficient space in the /boot partition. The biggest possibility is that multiple versions are occupied by the kernel upgrade. We only need to clean up the unused kernel files. Solution:
First check which kernels are available:
dpkg -l'linux-image-*' | grep'^ii' or dpkg --get-selections |grep linux-image
For example, on my VPS:
root@server-jp:~# dpkg --get-selections |grep linux-image
You can also use the "ls /boot" command to view which files are in /boot:
Uninstall the old kernel, the command is as follows:
sudo apt-get purge Linux-image-3.5.0-17-generic
Note: The green ones are to be uninstalled, everyone corresponds to your own, only keep what you need to leave!
