Mengatasi error “passwd: Authentication token manipulation error ” ketika merubah password di linux debian based OS

Bismillah ..

jadi error ini ketika saya ingin merubah password root di proxmox 7.2 aka debian 11 bullseye

[email protected]:~# passwd
New password:
Retype new password:
passwd: Authentication token manipulation error
passwd: password unchanged
[email protected]:~#

sudah banyak cara saya coba

[email protected]:~# chmod 0640 /etc/shadow
[email protected]:~# mount -o remount,rw /
[email protected]:~# pwconv
[email protected]:~# pam-auth-update

step di atas masih kurang atau tidak ber efek , terahir menggunakan perintah berikut

[email protected]:~# chattr -a /etc/passwd
[email protected]:~# chattr -a /etc/shadow

kemudian saya remove lagi password root nya

[email protected]:~# passwd -d root
passwd: password expiry information changed.

baru beri password lagi root nya

[email protected]:~# passwd
New password:
Retype new password:
passwd: password updated successfully

semoge bermanfaat
