[Resolved] Unable to login, no method works

Hey everyone!

So I've been running Arch for longer than 2 years at this point. I'm definitely not an inexperienced user, as I like working with the system.
Just a few hours ago I've upgraded my system, restarted it because I was unable to install the packages listed in the "wine-osu" AUR package, and I was unable to login again. I did NOT forget my password, as I've been using this one for my machine for at least over a year now.
Upon trying to use "sudo" with my user on a live usb chroot'ed into my installation I noticed that, as expected, the password still works.
Since I don't remember if I have told PAM to lock my account after a certain amount of tries to log in as a user, I tried to "reset" this by doing a "passwd -u" and also change the password of my account, root and a then newly created one.
Booting my installation again resulted in the same login failure as before, even after setting a very easy password that is near impossible to mistype. I also couldn't log in to the newly created account, and not even as root, so something is up.
I then again booted up my live installation, completely removed the passwords of all accounts in

/etc/shadow

after doing another "passwd -u" just in case, and it completely failed to ask me to provide a password for all three of the accounts tested and immediately told me my login was incorrect.
Another thing I tried was upgrading the whole system with

pacman -Syyu

, but that also didn't help.
I had a look at the output of

journalctl -xe

, but the only output I could find that was related to logging into my accounts was

Aug 19 18:26:37 navi login[493]: FAILED LOGIN 1 FROM tty1 FOR root, Authentication failure

.

I'm not at home and am writing this post from my Tails Live Installation, and would very much appreciate any help I can get!

It looks like I have the same problem, as entering the correct password fails. However I am just started with Linux/Arch and need some guidance how to correct the problem with tally/tally2, how did you fixed it?

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

@Viev
boot the rescue.target or the installation iso, figure which file(s) in /etc/pam.d reference tally and edit them. Alternatively override them w/ the files provided by the package
("pacman -Qo /path/to/file" tells you which package owns a file and "pacman -Qkk pam" will tell you which files provided by "pam" are altered - you need to arch-chroot if you booted the install iso)

Thank you for you're guidance, I found the tally reference. Had setup a delay and lockout of user after three failed logins based on the wiki Lockout user after failed login attempts, after editing/removing that the system boots properly.

Thanks for the info.

I just booted from a pendrive and found a /etc/pam.d/system-login.pacnew file. Backed up the original file (with tally2 references in it) and replaced  with pacnew file.
After reboot I was able to login again.

Re: [Resolved] Unable to login, no method works

Thanks you so much for opening this thread!

The problem occurred yesterday after updating the system that it wouldn't let me login after rebooting.

Anyways I just removed any tally references from my system-login file located in /etc/pam.d and this resolved the issue. There are a couple more references in other files, but since I'm not using these methods to login I think it doesn't matter for now.
