I installed docker on my Synology NAS and installed ubuntu but I’m not able to change the password with passwd or chpasswd.
Enter new UNIX password:
Retype new UNIX password:
passwd: System error
passwd: password unchanged
chpasswd: (user root) pam_chauthtok() failed, error:
chpasswd: (line 1, user root) password not changed
I also googled a little but couldn’t find anything, that solves my issue.
Why do I need to change the password?
I want to install bind9 with webmin and that I can login to webmin I need the password.
