Login passwords incorrect on some newly installed 1.0.1 systems

Login fails with

Login incorrect

on a system newly installed from the 1.0.1 ISO image — on only some

reinstalls. Maybe it was my fault, but maybe not, it is kind of

spooky. Can others reproduce?

The first time the password was correctly set to x in /etc/passwd and

in /etc/shadow the line looked normal. Maybe I made a typo when

setting up the password?

I tried to reproduce with a less sensitive password “y” for root and I

believe an empty user password or maybe “y” too; now I got no user

entry in /etc/passwd and /etc/shadow but can log in as root.

This was the content of /etc/passwd:

Maybe I turned off my computer at the wrong time when booting into the

installed system? But the passwords get set up before the first boot,

don’t they? I reinstalled again since then. Now it works.

Hi!

"pelzflorian (Florian Pelz)" <pelzflorian@pelzflorian.de> skribis:

No. (I did many installs in VMs before the release… :-))

Note that you can check by doing an install in a VM using the attached

script.

So a password was set, as expected. Maybe you tried the wrong password,

or with the wrong keyboard layout?

Thanks,

OK. I consider it likely that a typo was the reason for the wrong

password on the first install.

However, the second install had no normal user account, as you can see

in my /etc/shadow (which is attached again). It should not have been

possible to install without user account. Now that I think about it,

I believe when I got shown the user account creation page in the

installer, I accidentally immediately pressed some key (maybe Enter)

and it threw me back to the locale selection. I configured everything

again, but I believe this was the reason no user account was created.

I could now make the user account creation page crash again by

entering a wrong password confirmation, but after going through the

installer again, the resulting config contains a user and I can login.

I do not know how I managed to break this.

Thank you. For now I’ll try on real hardware though.

Florian

Hi,

"pelzflorian (Florian Pelz)" <pelzflorian@pelzflorian.de> skribis:

Could you file a bug specifically for this one if you managed to

reproduce it?

Well that’s even better. :-)

Should we consider this bug closed?

Thanks,
