File system went read only after adding ssh key

I followed this guide to set up ssh key on my digital ocean droplet, but since I made step 4 my file system went read-only. I changed /etc/ssh/sshd_config from PermitRootLogin yes to PermitRootLogin without-password and then reload ssh; and when I logged back in, I had no writing rights anymore.

I can log in using ssh root@ but it does not ask me for any password, and I can not modify any file.

Before doing this, I upgraded my ubuntu from 12.04 to 14.04, it asked me during the upgrade which setting did I want for PermitRootLogin and when I looked at /etc/ssh/sshd_config after the installation (and after adding my ssh key) it was set on PermitRootLogin yes.

After a Power cycle I had nothing anymore. I went to the Consol Access and I had to reboot. Then it asked me if I want to solve some problems. I said yes, and it solved them. Thanks!

Run this, and give me the output:

fsck -n

Also, if it comes up with errors, you have 2 choices, with choice 1 being:

  • Power down the system
  • From DO control panel, put system into recovery
  • boot the system
  • from web console, run “fsck -yf /dev/vda1”. If that fails, run “fsck -yf /dev/sda”
  • power down the machine after it completes
  • exit recovery mode
  • power system back up

Second choice is as follows:

  • Open up web console
  • reboot system
  • boot into single user mode
  • run fsck -r
  • reboot
