Setelah berbulan-bulan ecryptfs berfungsi dengan baik telah rusak dan ditampilkan /home/ tidak dapat diakses. Saat menjalankan (baik melalui akun tamu dan dari live-CD):
[email protected]:/media/backup/home/me# ecryptfs-mount-private
ERROR: Encrypted private directory is not setup properly`
Saya kemudian mencoba:
[email protected]:/media/backup/home/me# ecryptfs-recover-private
INFO: Searching for encrypted private directories (this might take a while)...

Ini membuat 124 folder terenkripsi yang tampaknya menyimpan /home/ saya data. Saya hanya tidak tahu cara mengakses data ini. Selain itu, melihat /var/log/syslog/ ada banyak kesalahan berikut:
Dec 3 11:19:22 ubuntu kernel: [ 1627.918209]
ecryptfs_parse_tag_70_packet: Error attempting to find auth tok for fnek sig [1b62c525049b45e0]; rc = [-2]
Dec 3 11:19:22 ubuntu kernel: [ 1627.918214]
ecryptfs_decode_and_decrypt_filename: Could not parse tag 70 packet from filename; copying through filename as-is`
Saya sangat ingin mendapatkan ecryptfs bekerja kembali dengan benar atau setidaknya memulihkan data saya.
Jawaban yang Diterima:
Setiap kali saya mencoba menggunakan frasa sandi MOUNT, saya juga mendapatkan kesalahan ini (folder rumah terenkripsi saya tidak rusak):
[ 2977.052719] ecryptfs_parse_tag_70_packet: Error attempting to find auth tok for fnek sig [2e1f1a0ca6f5f8f3]; rc = [-2]

Saya berhasil memasang folder rumah lama saya hanya dengan menggunakan frasa sandi LOGIN, yaitu kata sandi asli yang Anda gunakan saat pertama kali membuat folder rumah ecryptfs Anda.
