Alhamdulillah bertambah lagi 1 pengguna BlankOn, sahabat yang sudah saya anggap seperti saudara sendiri, memberikan kepercayaan kepada BlankOn untuk menjadi sistem operasi utama di laptop pertamanya. Dari 2 distro linux yang saya tawarkan dan telah dicobanya secara live, dia lebih memilih BlankOn 9 daripada Ubuntu 13.04. Pemasangan BlankOn lancar jaya. Karena ISO yang saya punya adalah ISO sesaat setelah rilis (saya unduh tanggal 18 Februari 2014), maka saya merasa wajib untuk memperbaruinya. Upgrade tidak masalah, walau sebenarnya ada kendala koneksi yang kebetulan meng-keong. Pemasangan virtualbox inilah masalahnya. Pemasangan menemui unmet dependency.
{% highlight bash %} You might want to run ‘apt-get -f install’ to correct these. The following packages have unmet dependencies: linux-image-3.0.7-1-generic : Depends: wireless-crda but it is not installed linux-image-generic : Depends: linux-firmware but it is not installed E: Unmet dependencies. Try using -f {% endhighlight %}
Sesuai permintaan, tambahkan opsi -f, tapi………masih error saudara-saudara!

Hm….gimana ya caranya? Yang saya suka dari linux adalah ketika error linux menawarkan solusi dan menampilkan pesan error / errornya itu kenapa. Menawarkan solusi ya itu tadi dengan menambahkan opsi -f. Solusi ini sudah dicoba tapi kok masih gagal? Mari kita lihat errornya itu di mana. Perhatikan proses installnya, output apa yang dihasilkan? Kalau dicermati, kegagalan installasi adalah karena gagal meng-overwrite /var/cache/apt/archives/wireless-crda_1.14_i386.deb dan /var/cache/apt/archives/linux-firmware_2.1_all.deb, perhatikan ada “trying to overwrite”.
Sebab kegagalan sudah ketemu, langsung kita coba atasi. Kita akan melakukan overwrite secara paksa.
{% highlight bash %} $ sudo dpkg -i –force-overwrite /var/cache/apt/archives/wireless-crda_1.14_i386.deb ; sudo dpkg -i –force-overwrite /var/cache/apt/archives/linux-firmware_2.1_all.deb {% endhighlight %}
Alhamdulillah berhasil.
