Ubuntu, /boot penuh sehingga gagal update

Posted by Prayitna Kuswidianta on 10th July 2015

Server Ubuntu memakai versi 12.04, sudah lama dipakai dan terhubung dengan internet secara NAT.

Untuk detail release dapat dilihat sebagai berikut :

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04 LTS"

Dengan konfigurasi /boot yang kecil, maka untuk hari ini diketahui sudah penuh

# df -h

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vmhoat232-root 127G 84G 37G 70% /
udev 3.9G 4.0K 3.9G 1% /dev
tmpfs 799M 352K 799M 1% /run

none 3.9G 0 3.9G 0% /run/shm
/dev/cciss/c0d0p1 228M 206M 11M 96% /boot

Apabila dilakukan update akan berakibat gagal, seperti pesan berikut ini :

# sudo apt-get update
