If I reset my password will this update the passwd file?
The reason that I ask is because I foolishly edited my /etc/passwd manually and in the process deleted the root user line. Now I am unable to use sudo to edit the file.
My solution is to purchase a new droplet and replicate my existing server. However I am not sure if this is truly necessary. I am fairly new to server admin, hence the foolish behaviour of manually editing my passwd file! Any info would be greatly appreciated.

No, resetting the password updated /etc/shadow where the password is actually stored.
Follow Attempt Recovery with a Recovery ISO | How To Recover from File System Corruption Using Fsck and a Recovery ISO | DigitalOcean. You can skip the Set Up Networking in the Recovery Environment section.
Once you’ve mounted the filesystem, open /mnt/etc/passwd in nano or any other editor, and add the following line at the beginning:
root:x:0:0:root:/root:/bin/bash
Then, save the file, unmount the filesystem, and power off the droplet:
cd /
umount /mnt
poweroff
Finally, reply to the support ticket to remove the ISO image from the droplet so you can then boot your droplet normally.
Hi, Just want to say a big thank you for your help on this issue. Finally, after a month I got round to fixing this.
Yes, resetting your root password can potentially help, but it won’t directly restore the missing entry in /etc/passwd. When you change the password using a reset tool it typically updates the password hash in /etc/shadow, but it does not restore the /etc/passwd file, which contains essential account information like user IDs.
Since you’ve deleted the root user entry, your system won’t recognize the root user for logins or any root-level operations like sudo.
You can boot into a recovery or rescue mode where you’ll have access to the filesystem without needing root or sudo permissions. Here’s what you can do:
/mnt or /media)./etc/passwd file to restore the root user line.root:x:0:0:root:/root:/bin/bash
Then save the file and reboot back into normal mode.
If you have any backups or snapshots of the system, you can restore the /etc/passwd file from there.
If you’re completely locked out and cannot get into recovery mode, you could spin up a new droplet and replicate the setup from your current system. You can still mount the old droplet’s filesystem in recovery mode and copy important data to the new droplet.
