Why are my user accounts missing from login screen after upgrade to 14.04 from 12.04 ?

Upgraded my 12.04LTS to 14.04 LTS via DVD, choosing the "upgrade" option from the installation options prompt.

Since then, in the Login screen, the older user accounts are not visible. They are however visible if I navigate to the home screen. Those are protected and even as admin

Below is the output of grep /bin/bash /etc/passwd :

root:x:0:0:root:/root:/bin/bash
admin1:x:1000:1000:admin,,,:/home/admin1:/bin/bash
dranand:x:1001:1001:Anand Philip,,,:/home/dranand:/bin/bash

Here is the output of ls -l /home. (The new profiles I have created during the upgrade are marked.)

drwx------ 18 admin1  admin1  4096 Apr 21 17:35 admin1 [NEW]
drwxr-xr-x 21    1004    1004 4096 Apr 11 12:48 dmishariff [OLD]

How do I solve this?

I had a similar problem. I was upgrading from Ubuntu 13.10 to 14.04 and it crashed mid way through the process. I ended up reinstalling Ubuntu from a USB drive and chose the option to keep my files and users but ran into the same issue that you're having.

The following worked for me:

1. Create a new user with the same exact username as the one lost.


2. Open Terminal


3. id -u username


4. My uid was 1001 shown in example below, replace this with your uid.


5. sudo useradd --home /home/username --uid 1001 --gid users username


6. sudo chown -R username: ~username
