Linux Login Screen Stuck [System Brick] (Ask for login-name forever)

Hey,

I do not understand how it is, I can not login to the system anymore.

When i type "root" or "dentrax" (my username) at the "arch login", waits ~10 seconds and does not ask for a password. It is continuing to ask for login name again forever even when i type "root".

The system boots normally (grub still works fine) and the welcome screen is still running when booting.

I accidentally "git init" into the home directory and removed that folder. I do not remember what I did later but I certainly did not "rm -rf /". It actually does this by vscode. When I opened the vscode, there was exactly 5k+ of file-stage waiting. ZSH was broken when I pressed the discard-all button on vscode's github plugin, but everything else was working smoothly. I was able to read and write the files on /home. All programs were opened except for zsh. This problem occur when I re-booted the system.

-Unable to login console

Can someone please help me? How do I log in to the system?

Change_root in from the installation media and check the journal for the cause of the login failures.

Hey,

I don't bit-quite understand, What exactly is "installation media"? Do you mean "ArchLinux Bootable USB"? I also tried a few things on Grub...

I added init=/bin/bash

I got this:

Finally, Is there another way out there, just curious? Why am I experiencing-getting this issue-problem? What is causing this problem?

Yes,  you can post text from the console using the tip from List_of_applications#Pastebin_clients

Yes, installation media is a bootable usb.  As for your image, I'm only getting an access denied from that website.

As for finding the cause of the problem, that is the goal of a troubleshooting thread.  Once we know the cause, we'll have a solution.  But you need to help us find the cause.

I have a hard time understanding your initial post as there are a lot of vague pronouns.  For example, you say "It actually does this by vscode" but I have no idea what 'it' or 'this' are referring to.  Please describe the background/history clearly keeping in mind we are not sitting at your computer.  Then boot with the bootable usb and chroot in to your system to collect logs.

Today I tried to login rootfs using init=/bin/bash on booting. After that, i tried "export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin" then, "mount -n -o remount,rw /" later i type, "passwd" and i have still same error: "passwd not found"

After that I did live-usb using Rufus with archlinux-2018.04.01-x86_64.iso (4.15.14) After that, i can't figure out what i should do after login with "root@archiso".

https://wiki.archlinux.org/index.php/re … t_password

This is exactly what I don't understand: "Boot the LiveCD and mount the root partition of your main system." and "Use the passwd --root MOUNT_POINT USER_NAME"

What does "mount the root partition of your main system" mean? How can i mount my main system with commands?
What sould i type for "MOUNT_POINT"?

Re: Linux Login Screen Stuck [System Brick] (Ask for login-name forever)

The section you link to contains a link on how to mount, if confused by following steps you should follow that link.

However I find it hard to believe that you've managed to install Arch while being confused by these instructions. Which instructions did you originally follow to install Arch?

Re: Linux Login Screen Stuck [System Brick] (Ask for login-name forever)

Finally, i successfully mount my /sdc3 to /mnt. I can see my main / files at /mnt.

My root passwd uses /bin/zsh, but there is no zsh at /bin? But the system needs to have a "zsh" file. How can i change login shell to bash? (chsh not works)

And when i type "passwd --root /mnt dentrax"
Output:
passwd: Module is unknown
passwd: password unchanged

How can i fix these problems? @V1del

Dentrax, you can simply edit your /etc/passwd file - it is a plain text file just find out line according your user name and edit the field
EDIT: after mounting your root directory to /mnt edit /mnt/etc/passwd

Re: Linux Login Screen Stuck [System Brick] (Ask for login-name forever)

Here is what i have done:

1- I booted the LiveUSB and mount the root partition of my main system. (mount /dev/sdc3 /mnt)
2- I've checked every .log file on the /var/log path. (I couldn't find any log to interfere with the entry.)
3- "UTMP, WTMP and BTMP" files are creating when I am trying to log in to the system. (The contents of the UTMP and WTMP files are empty)
    When i run "utmpdump /var/log/wtmp" It's just logging about my login attempts. (Doesn't contains information about errors.)
4- I have changed my "/mnt/etc/passwd" input shell with "/bin/bash" instead of "/bin/zsh" for accounts "root" and "dentrax" (also tried /bin/sh) (Also changed my default shell to bash with chsh)
5- I have changed my "root" and "dentrax" password to "1"
6- Also i checked my .bashrc, .bash_profile and .profile files. There's no any problem preventing login input. All in default configuration.
7- Also I tried to remove the password from /etc/shadow file.

Finally, the problem still goes on. When I boot the system and enter the login username, system waits ~10 seconds and nothing happens and asks for the login username again. (forever loop) The login password prompt question NEVER comes up.

(Note: Sorry for top message, I wrote the wrong question in the top message. (: )

I would like to ask you, how do I solve this problem? Because I have work to develop on the system. I would also remind, that question is on the "Newbie Corner". Can we focus on the question, please?

Re: Linux Login Screen Stuck [System Brick] (Ask for login-name forever)

Change_root in from the installation media and check the journal for the cause of the login failures.

Systemd#Journal  please post the output from the journal for a boot with the issue.
List_of_applications#Pastebin_clients tip box provides instructions to post the output to a pastebin from the console.
Edit:
Also post the output of pacman -Qkk.

I think my issue is: "can't exec /bin/login: No such file or directory". When i type: "stat /mnt/usr/bin" i get the output that file is there.

Thank you so much! Login issue is completely fixed now.

Fix:
(do this after the mount main-system)
Type on /mnt : "ln -s usr/bin bin"
