Re-Enabling User Account After Upgrading Ubuntu Linux from 10.10 to 12.04LTS

Just upgraded a desktop PC from Ubuntu 10.10 to 12.04LTS using CD install (online update failed).

I am able to boot up into the new account (which I called test) I created during the upgrade. But I cannot log into the original account (called richard).

From Terminal, I see there is a /home/richard directory where I can see all the user files.

How can I re-enable that richard account?

see if richard is actually in /etc/passwd

If it is not, re-add the user.

useradd -d /home/richard richard

Thank you, Arnold.

No, richard is not in /etc/passwd

Does "useradd -d /home/richard richard" just add that required entry into the passwd file? Or does it create new directories? Obviously I don't want the original /home/richard directory to be over-written. Excuse my inexperience. Not very well-versed in Linux.

Then you'll need to add richard as arnold points out.

Then check the home directory and if the uid / gid is the same as your previous installation.. You can check this using :

ls -al /home

Open in new window


If richard directory is owned by user and group richard then it is the same uid/gid with your recent system. But if you see it is owned by another user or just see a number instead of uid/gid then you'll need to change owner of the home directory to richard using this command:

chown -vR richard:richard /home/richard

Open in new window


This should do to set the user home owned by the new richard account.

Cheers,
K.

I'm getting the error, "useradd: cannot lock /etc/passwd; try again later." when I enter "useradd -d /home/richard richard" in Terminal.

When I enter "ls -al /home" these are the results:

drwxr-xr-x  5 root root 4096 Jun  7 19:22 .
drwxr-xr-x 24 root root 4096 Jun  7 19:40 ..
drwxr-xr-x 56 test test 4096 Jun  7 18:45 richard

Oh wait. Ran "useradd -d /home/richard richard" using sudo and this time it worked.

OK. I've now managed to get richard to show up as one of the login items when I first start Ubuntu. But then it wouldn't accept the original password for this account. So I ran "sudo passwd richard" to reset it.

Now it accepts that password. However, after it spends around 5 seconds trying to get to the desktop, it simply dumps me back at the initial login screen.

Just ran "chown -vR richard:richard /home/richard" to change ownership as per KeremE's suggestion.

Going to try logging out of test and back in as richard.

Don't like Unity desktop.

How can I revert 12.04 back to Gnome desktop?

Likely when it upgraded it asked whether to retain existing user or create new one,
It seems the passwd file was overwritten.
You need to run sudo passwd richard to set a new password.

This should be it.
The useradd reset the gid/uid on the directory when it already exists.
