Actually this happened after I upgrade to Lenny from Etch. I found the brutallity problem solving from google at one of LinuxQuestions thread.

And I try it:

Enough adalah cukup untuk unrar-free yang selama ini gue gunakan untuk mengekstrak berkas .rar. Selama ini setelah unduh file .rar, coba ekstrak eh tapi seringnya gagal. Gue pikir memang berkas tersebut corrupt yang pada akhirnya, ah sudahlah cari yang lainnya pun memang berkas tersebut tidak begitu penting. Ternyata belum tentu demikian. Tersangka utama merujuk pada perangkat pengekstrak .rar, unrar-free, yang gue pakai.

Kemarin, Tub sempat berbagi berkas .rar di ngebut. Setelah selesai unduh, gagal ketika ekstrak^[1] . Padahal Tub bisa^[2] dan padahal gue juga unduh dengan bantuan wget yang dimana 99% pasti berhasil tanpa berkas tersebut korup.

Setelah cari di internet, gue dapet perangkat bantu unrar^[3]. Yang gue lakukan pada saat itu adalah dengan menambah daftar di source.list (/et/apt/source.list).

deb http://mirrors.kernel.org/debian etch main non-free

Setelah itu, apt-get update dan dilanjutkan dengan apt-get install unrar. Selesai.
