Installing Snapshot always fails with "failed to set user account password" error [Solved]

[dolphin_oracle]

looks right

I'm going to test a kde snapshot. anything special to do to mimic your case? any PAM changes or anything like that?

Thanks a lot. No, just installing a bunch of the usual software and some look & feel changes in the KDE settings. I set up my initial installation with a single user and also set an administrator password. Nothing else.
If you need any logs, config files etc. to reproduce the issue I'll be happy to upload them here.

hmm...

before installing, on the live-usb, try

Code: Select all

pam-auth-update

and see if it looks like this:

click next to cycle through the interface.

No, it looks very different (see below). There is no "next" button, when I click "continue" the window closes. Also, when executing the command and clicking "continue" there are error messages in the terminal:

Code: Select all

stefan@HP-Linux:~
$ pam-auth-update
debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied
open(/var/lib/pam/seen) failed: Permission denied at /sbin/pam-auth-update line 238, <STDIN> line 12.
debconf: DbDriver "config": could not write /var/cache/debconf/config.dat-new: Permission denied

Edit: The error message do not appear when I execute the command with sudo, but the window looks the same.

[dolphin_oracle]

oh, use sudo. my fault.

Code: Select all

sudo pam-auth-update

[SIttner76]

Code: Select all

sudo pam-auth-update

OK thanks, see above. The window stays the same, but the error messages disappear.

[dolphin_oracle]

ok that looks correct then. did you click all the way through? there are some reports that will correct a corrupt PAM config file somewhere and eliminate the error a chpasswd. its worth a shot.

BTW I have not duplicated the issue on a KDE snapshot.

If I click on "continue" the windows just closes, there is no second page. As I said, it looks different than your window in that there is no "next" button.
Edit: I tried installing the system after running the command and clicking "continue", but it fails with the same error as before

Code: Select all

2022-03-13 20:17:38.154 DBG default: SErr #136: "chpasswd: (user demo) pam_chauthtok() failed, error:\nAuthentication token manipulation error\nchpasswd: (line 2, user demo) password not changed\n"

Note: I did not set the user account to "demo" during the installation but used my own user name

At least I can reproduce something which creates an error message,
which appears to be identical ( shown here with line breaks):
This command:

Code: Select all

printf 'fehlix:x\ndemo:x' | chpasswd

sends two lines to chpaswd:
line 1 succefull for an existing user "fehlix" ,
line 2 failes for non-existing user "demo":

Code: Select all

chpasswd: (user demo) pam_chauthtok() failed, error:
Authentication token manipulation error
chpasswd: (line 2, user demo) password not changed

So somehow user "demo" seems to be involved within the installer , where user "demo" does not exists on the installed system.

[dolphin_oracle]

hmmm....more than one user on live system maybe? those files would copy over...
