Questions[passwd](ubuntu)

for some reasons my already stored passwords are not visible under saved passwords, it just shows "saved passwords will appear here"

but they are there, the sql file is where it should be, chrome and Chromium behave identically:

• for new site passwords is popping up the dialog "save password", after confirming the autofill is working
• for changed passwords is popping up the dialog for change password and after autofill is correctly working

has apparently nothing to do with the keyring password, I can delete it and autofill keeps working FINE, seems Chromium was using an encrypted password while Chrome used a plain text password, I believe that was because before installing Chrome for checking it out I removed all kwallet files, (I use KDE Plasma ) reinstalling after didn't caused any change

the Chrome settings are correct and the problem appeared some upgrades ago but came to my knowledge when I needed to remember a password, now I am with Chrome 84.0.4147.125 and Chromium 85.0.4183.59

just to complete they are no on Google and sync was never activated

also interesting renaming the passwd sql file and starting Chrome or Chromium, they asked for save the credentials and then the show up, but that is no solution to the problem why the old ones are not showing up

would be very nice if somebody has an idea to solve this

I am in a bizarre situation, that I can't reset user's password on my machine (Ubuntu 16.04) using eighter sudo passwd username or passwd username from the root account.

root@adam-minipc:~ # passwd mikolaj
Current password: 
New password: 
New password (again): 
passwd: Authentication token manipulation error
passwd: password unchanged

In the /etc/shadow the relevant entry reads:

mikolaj:!:18063:0:99999:7:::

Why is that? What cause it and how to reset the password already? Have I been pwned?

Unlocking the account does not help either:

root@adam-minipc:~ # passwd -u mikolaj
passwd: unlocking the password would result in a passwordless account.
You should set a password with usermod -p to unlock the password of this account.

usermod -p <encrypted password> mikolaj requires encrypted password, and it simply pastes it to the /etc/shadow file. I don't know how to get the encrypted password, even if I knew, it must be a way to simply reset a password if you are root. It is the first time I see this behavior of passwd and frankly I am really at lost.

The question is different from Getting an "Authentication token manipulation" error when trying to change my user password, because it has nothing to do with the read-only file system, nor I complain about the error in the first place. I want to know, why sudo passwd <username> suddenly started asking for a current password. On all my other systems it doesn't.

I'm attempting to migrate an OpenVPN server from a CentOS box to an Ubuntu 18.04 one.

There is a script which creates new VPN users. Part of this is that it generates a new password for the user and then passes this in as the Linux password for the new user (there is MFA on top of this so this is only one part of the authentication process).

However the script uses the following line to do this:

echo ${VPN_PASSWORD} | passwd "${VPN_USER}" --stdin

And after messing around for a long time I've discovered that Ubuntu doesn't have the --stdinoption for passwd.

What I haven't been able to find, however, is an alternative way of doing this.

These are the relevant parts of my script.

We generate a password:

VPN_PASSWORD=$(cat /dev/urandom | tr -dc 'A-Z0-9' | head -c 8)

We add a new user and attempt to assign this password to it:

echo "Adding Unix user ${VPN_USER}"
useradd -G vpnusers -m -s /sbin/nologin $VPN_USER
if [ "$?" != 0 ]
then
    echo "Could not create user. (Are you sudo?!)"
    exit 1
fi

echo ${VPN_PASSWORD} | passwd "${VPN_USER}" --stdin
echo "User created."

The user is being created but I'm getting this error regarding the password:

passwd: unrecognized option '--stdin'
Usage: passwd [options] [LOGIN]

I've been trying for a day to find and answer to this and tried many, many things but I think my fundamental lack of Ubuntu knowledge is the real issue here.

I want to change my default shell from tcsh to bash. So I tried and this is what happened:

>sudo chsh userid
Changing the login shell for userid
Enter the new value, or press ENTER for the default
        Login Shell [/xhbin/tcsh]: /bin/bash
chsh: user 'userid' does not exist in /etc/passwd

Indeed, I am not in /etc/passwd. I don't know why.

What can I do?

I am running Ubuntu on a Oracle Vbox in Windows 7 to develop a website. I have a set of directories that have owner read/write permissions but the group www-data does not have rights on the directories.

I tried the command sudo chmod 640 /path-to-directory to change the status, but receive a message requesting my www-data password. My owner level password does not work and I do not know what this password might be.

I tried passwd and receive the message 'changing the password for www-data and a prompt for my current password. When I enter it, I get this error message:

passwd: Authentication token manipulation error
passwd: password unchanged

This error message looks more like some sort of problem on my system, but everything else works fine.
