Menghapus Kernel Lama di Ubuntu - BackBox Linux

Sebenarnya tutor ini sudah banyak tersedia di google. Namun saya sengaja posting di blog ini untuk arsip saya sendiri, biar mudah kalo nyari refrensi.

Oke kali ini saya akan share cara Menghapus Kernel Lama di Ubuntu - BackBox Linux.



Pertama, masuk terminal sebagai root.

jackwilder@yunivita ~ % sudo su 

[sudo] password for jackwilder:



lalu masukkan command berikut untuk melihat kernel berapa saja yang terpasang.

root@yunivita:/home/jackwilder# dpkg --get-selections | grep 'linux-image'

linux-image-3.13.0-36-generic            install

linux-image-3.17.4-031704-generic        install

linux-image-3.18.0-031800-generic        install

linux-image-extra-3.13.0-36-generic        install

linux-image-generic                install



Kali ini saya ingin menghapus kernel 3.17 karena saya sudah mengupgrade ke kernel 3.18 ( kernel yang dipakai saat ini.

Sementara , kernel 3.13, bawaan dari BacBox 4.0 biarkan saja.

Sudah.. ? Uppss.. belum.

Ada lagi yang harus kita remove, yaitu linux-headers nya.

Berhubung yang saya re move tadi adalah linux-image kernel 3.17, maka untuk linux-headers nya juga harys yang 3.17.
