Saya mencoba bunzipping dan mendapatkan jejak sampah:
bunzip2: us.archive.ubuntu.com_ubuntu_dists_vivid-updates_main_binary-i386_Packages.bz2: trailing garbage after EOF ignored
Sepertinya file yang dikompresi hanya 88K:
du -hs us.archive.ubuntu.com_ubuntu_dists_vivid-updates_main_binary-i386_Packages
88K
Melakukan dump hex pada akhir file muncul untuk mengungkapkan daftar direktori yang ditambahkan:
