Raspberry pi emergency mode cannot open access to console

Raspberry pi emergency mode cannot open access to console DEFAULT

Rescue RPI with “Cannot open access to console, the root account is locked.”

If your Rasberry Pi (RPI) won’t boot and is showing “Cannot open access to , the root account is locked.”  on the boot screen.

Don’t sweat. It can be fixed with a little work.

You were probably editing /etc/ and have put in an unsupported entry. What’s happened is now on next boot it’s tried to load this entry, which doesn’t work, and it’s locked the Pi from starting up.

To fix this get your SD card out of the RP and plug it into your computer. Ignore the requests to format the card (don’t format it or you’ve lost everything). One of the drives will have data on it and you will see a file called cmdline.txt open this text file in Notepad or similar and add the following text to the start of the first line init=/bin/sh

Save the file and put the SD card back into the RPI and power it up. You will need a keyboard plugged into the RPI for the next step and be viewing the output via HDMI.

Part way through startup the pi will now switch into bash (the console). This will enable you to go and fix the /etc/ file. If you were messing with that in the first place then you should already know how to use the command line, so I cover that here. Essentially what you need to do is:

  • nano /etc/
  • remove the faulty line (ctrl+k to remove line)
  • Save the file
  • Take the SD card back out and remove the init=/bin/sh from the
  • Reboot the Pi and it should now work fine

However, sometimes you be able to write to the file and may need to remount your partitions. You can do this by running

  • mount -o remount, / –target /

before the steps above.

[Howto] Cannot open access to console, the root account is locked in emergency mode (dracut emergency shell)

This is a known problem. It happens Fedora releases 28 and newer, which don’t require password for root account during installation and use first user added as administrator/superuser. In this case root account is locked, and if is inaccessible – then the system can’t use superuser/administrator account either.

If you find yourself in this situation and you can’t resolve problem with mounting from Live disk/USB, and you need access to emergency mode, the solution is simple.

  1. Boot into Live disk/usb and chroot into your Fedora installations as documented in this Fedora quick-docs article – following steps 1 through 8.

  2. Unlock root account by supplying password for it:

  3. Exit chroot environment with [Ctrl-d] or

  4. Reboot your computer with GUI or with

You should get back to emergency mode but with perfectly functional shell/console.

Linux / Raspberry Pi [3B,3B+,4] Emergency mode root account locked [Solution]

I restarted my Raspberry Pi today and wondered why after 5 minutes I still could not connect to my Pi via SSH. I’ve plugged a monitor and had the following error message:

The problem

I had a hard drive connected to my Raspberry Pi and mounted it. Then i’ve set up an automount via fstab. The problem was that I had a typo in it. I had entered txt4 instead of ext4 and that caused a total failure. Here is a screenshot:

The solution

First, we have to get to our system. We do that through the so-called minimum shell environment.

For this purpose, we turn off our Raspberry Pi, put the memory card in another computer and open the boot partition of the memory card. There we find the file cmdline.txt We attach following to this file:

We do not create a new line, just add the above command to the same line! In the end, the structure should look like this: ... elevator=deadline rootwait init=/bin/sh

After we have done that, we save the file and put the memory card in our Raspberry Pi. It is booted into the minimum shell environment.

Currently we are in “read only mode“. We get the write permission by mounting the root partition in read-write mode. This is done with the following command:

Here you will maybe notice that the keyboard layout does not correspond to your keyboard layout. Here is a picture of the layout you will need:

Now we are in read-write mode. This means we can edit fstab with the following command:

In fstab we now have to make the desired changes. I would recommend that you just delete the broken line and continue working in the right system via SSH.

When we have finished the file, we end the editor with Ctrl+X and confirm our changes.

Then we enter the following command twice:

After that we finish our work with:

You will receive many panic messages but do not be scared of it.

Now we can unplug our Raspberry Pi, put our memory card back into another computer, open the cmdline.txt in the boot partition and take out the previously added command (init=/bin/sh), save it and put the card back in our Raspberry Pi. Finished!

Replying to comment above

The Problem

The temporary workaround - Setting last field to '0' in /etc/fstab - is a terrible idea

After I set it to '0', on the next dirty shutdown and subsequent boot, a huge problem surfaced.

The root file system was being mounted as read-only.

Found this and this, which explained the situation clearly

The default behaviour for most Linux file systems is to safeguard your data. When the kernel detects an error in the storage subsystem it will make the filesystem read-only to prevent (further) data corruption.


perhaps it is because the disk is unclean, try changing:
/dev/sda1 / ext3 defaults 0 0
/dev/sda1 / ext3 defaults 0 1
or at least do an fsck and then reboot

The Solution

  • The obvious solution was to revert /etc/fstab to its original state, and run fsck to clean the filesystem
  • However, I could not write to /etc/fstab, since the file system is read only.
  • I tried to remount the filesystem as with write permission, following this
  • That didnt work either. Got this error.
    • mount: / not mounted or bad option
      In some cases useful info is found in syslog - try
      dmesg | tail or so.
  • dmesg told me this
    • EXT4-fs (mmcblk0p2): Couldn't remount RDWR because of unprocessed orphan inode list. Please umount/remount instead
  • Found this answer which solved the orphan inode problem.
  • After that, e2fsck asked me to reboot. After the reboot, root was clean and had write access by default.
  • To avoid future chaos, I reverted /etc/fstab to its original state.

The Conclusion

So, we still don't have a solution for the original issue. Need to work on it.
