Lost password after upgrade/update

jschall · 2016-09-27 18:05:09

I had been away from BunsenLabs for months, so I decided to update then upgrade.

Alas, when finished and rebooted, it will no longer accept my username/password.

I tried going into Recovery and ran the passwd command, but on reboot it still refuses both old and new passwords.

Is there a default username/password following an upgrade?

Or do I have to completely reinstall Bunsen?

No, there should be no alterations of that nature during a normal upgrade.

Is the home folder for the user still present?

Are you sure that your keyboard is configured correctly?

Can you log in to a console screen if you press <Ctrl>+<Alt>+F1?

If you can then check this post:

i hope you understand that there's very little WE can do about it.
obviously - how safe would your system be if it had some sort of backdoor when you borked your passwords?
i suggest trying the obvious: is caps lock on on the keyboard? are you using non-standard characters like öäåú? is the keyboard just stuck or broken maybe?

I tried going into Recovery and ran the passwd command, but on reboot it still refuses both old and new passwords.

HOW exactly did you do this? please show us.
the correct command to change your USERS password would be:

passwd <username>

so, assuming your username is jschall:

passwd jschall

from a root prompt.

Is there a default username/password following an upgrade?

no such thing. ever.

Remember folks, physical access == root access

Physical access means anything is possible.

i'm sorry i forgot to mention this.

jschall, when the hard drive partition in question is not encrypted, you can always access and modify your data, and this includes modifying passwords to my best knowledge (i have never been in a situation to be forced to try that).

[ot]i very recently answered another user's cry of outrage when they discovered that they'd locked themselves out of their server after changing ssh login method to keys - i guess my answer was influenced by that.[/ot]

Thank you for all the suggestions. I am able to get a root terminal, but even after running "passwd jeff" succesfully, I still can't login.

I guess I will just re-install :-(

What exactly does the error message say? Can you then not log into your user from lightdm and the tty terminals?

Anyway for you to check your journalctl logs?

jschall · 2016-09-29 17:06:16

@Horizon_Brave: The message said "password incorrect". I don't know what "lightdm" is. I re-installed.

LightDM is the display manager that ships with BunsenLabs Hydrogen, Debian Jessie LXDE, and several other distros based on Debian Jessie that either have lightweight Desktop Environments or are build primarily on a desktop-free Window Manager like Openbox.

Understanding the differences between LightDM, GDM, KDM, and whatever else is lurking out there is important when choosing a distro and/or desktop environment. I've been out of touch for a couple years, so I just stick with what's in Debian stable (currently Jessie) LXDE. O:)

That is *not* what I suggested in my post, read it again:

The solution to your problem is (or rather was) contained in that link -- a configuration file used by LightDM has changed and a simple edit of a single file is all that is (was) required to fix it.

I'm not sure if this is relevant , but I experienced " Rejection " at log in stage ( both main start-up / and after screen saver )

I realized it occasionally Broke ,noticing a pattern .
It disliked mixing Keyboard entry and mouse clicks

( Maybe my password has a "Carriage-return/Enter-key" on end )

Navigating with just key-board and pressing ENTER key got better results
than clicking Login button with mouse ..after using keys to enter !

( This was on an Partly-broken-by-end-user "Install" ..and may just be
a qwirk ) ( -or my mouse is just NAFF- )
