useradd: cannot lock /etc/passwd; try again later.

I didn't even want postfix installed, the auto update program decided it was a new dependancy of google-chrome. The update failed and google chrome was removed.

Same issue as reported by Robert.

This issue started for me originally with Jetty I think, I didn't have the ability to submit a bug report at the time. I began receiving an error about how it couldn't setup a Jetty user account. This is the data in /var/term.log for the latest update.

Seems to actually be a problem with chrome-beta and the prereqs it has.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in postfix.
For future reference you might be interested to know that a lot of applications have bug reporting functionality built in to them. This can be accessed via the Report a Problem option in the Help menu for the application with which you are having an issue. You can learn more about this feature at https://wiki.ubuntu.com/ReportingBugs.

The root of the problem is:

useradd: cannot lock /etc/passwd; try again later.

Have you changed /etc/passwd? What are the permissions on the file?

This is not a bug in postfix.

From what I could tell the passwd.lock and shadow.lock files had not been removed. I don't remember the permissions but they looked correct at the time. I can no longer reproduce the error as I have reloaded my machine for a separate reason.

I'm having the same problem trying to install open ssh server off a fresh install although it is set up with nss to use ldap. The file permissions are the same as on the other computers, fuser displays no processes using the file and lslk also displays no locks. The groupadd and groupmod work but the other user admin tools such as userdel don't. I've tried reinstalling the passwd package and the only error I can find in the system is from libcrypt. This was from a alternate cd install of 9.10 maybe it's best just to reinstall?

the same problem after install some packages
all installation programs ends with error by:

userdel: cannot lock /etc/shadow; try again later.

Just a note for any future bug reporter:

It is now clear that it happens that the passwd or shadow (or group, or gshadow) files can be locked.
The "me also messages" are not very useful (and will not make the resolution of this bug, if it is really a bug, any faster).

Please provide instead any information that could indicate why the files were locked:
 * the list of locked files:
    ls /etc/passwd.lock /etc/shadow.lock /etc/group.lock /etc/gshadow.lock

 * check the /var/log/auth.log for any message that could indicate the failure of any other tool (prior to the failure which reported the locked file)

 * any anormal operation on the machine (reset, shutdown while the computer is still running)

 * etc.

I had the same situation here, it turns out it was a stuck useradd process -
destroying it got useradd working again, something like this:

killall -9 userdel
rm -f /etc/*lock

In my case the stuck useradd was caused by a bug in my own script, but
for the others, if it was caused by the package manager then I guess there
might be a package out there with a bug in it's call to useradd.

I had the same situation on my ubuntu 9.10 Karmic , I was trying to add my user id to dba Group in order to star
and stop the DB services by own ,
raja@ubuntu:~$ usermod -a -G dba raja
usermod: cannot lock /etc/passwd; try again later.
i checked for any process locked the /etc/passwd file but found nothing .
Then i tried to run the command with sudo
this time it worked.

Might be a duplicate of bug 432964.

thnax for the solution............

It's been suggested that this might be a duplicate of bug 432964, which is described as "system crash in guest session locks /etc/passwd forever". Can the submitters of this bug and duplicates confirm whether they've used Ubuntu guest sessions on the affected system, and whether they saw crashes when doing so?

Nicolas, you comment in the other bug that we shouldn't clear locks on boot because they indicate something has gone wrong and shouldn't be ignored. While that's true, the trail on bugs like this is likely to be quite cold, and knowing the lock is there gives us only a slim chance of finding the cause. Since updates to these files are atomic and the lock files are used only to prevent two updates in parallel clobbering one another, there should be no file corruption and removing the locks should be safe - so I am inclined to say we should remove the locks at boot.

I'm not really worried by the consistency of single files (each one are updated atomically).

The problem is the inconsistency between files (e.g. /etc/passwd and /etc/shadow).
I'm not sure what would be the worst case if for example /etc/passwd is updated but /etc/shadow is not.

I think the absolute worse case would be an account locked out because
/etc/passwd has been updated with an 'x' but the corresponding entry has not
been added to /etc/shadow. But a) that can be guarded against by changing
the files in the proper order (which is probably already being done), and b)
having lock files left behind doesn't help solve any of the resulting
problems.

Otherwise, I don't see any real possibility of breakage caused by having one
file updated without the other.

This has turned up on the radar again because whoopsie tries to call adduser on upgrade to 12.04, and many users are finding their /etc/passwd locked. We should update shadow to clear lock on boot.

My upgrade to 12.04 has failed because of this.

I ve got an amd64 processor and using 64bit version, though.

What should I do get to get around it ?

*GNU/LINUX #553303*

Se libre usa software libre!!

Regarding #17 - I did just experience this problem but with /etc/group.lock instead of passwd. I did use a Guest session immediately before I discovered the breakage. The Guest account crashed when I attempted to play Open Arena, probably due to a fglrx bug. There was a leftover guest-???? group that I deleted.

Just got bit by this one again, clean lucid install. The fix is to "rm -f /etc/gshadow.lock".

"sudo do-release-upgrade" finishes with this:

The upgrade has aborted. Your system could be in an unusable state. A
recovery will run now (dpkg --configure -a).

Hello Chris, or anyone else affected,

Accepted shadow into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/shadow/1:4.1.4.2+svn3283-3ubuntu5.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

FYI: There is a typo on the changelog:

> * debian/passwd.upstart: Add an upstrat job to clear locks on
> [shadow-]passwd/group. (LP: #523896).

"upstrat" vs. "upstart"

No, it was not. The package in precise-proposed and is still pending

with this fixed will be removed from precise-proposed.

Please help to verify this update as outlined in comment #30 above.

Dmitrijs.

I suspect this is related to the "mountall" binary package?
Which deserves to be condemned to all hell.

How DARE the packagers INFECT a distribution with a binary
upon startup, other than the kernel?

The only binary code upon turning on any computer,
should be the kernel.

Everything else is utterly disgusting.

I could fix this myself if it wasn't for unbelievably
ridiculous shit like this:

On Ubuntu:

root@38r8:~# set |wc -l
6705

…on standard Debian:

4r6s1:~# set | wc -l
50

…really? *Really*?

I installed the versions of passwd and login from precise-proposed and followed the testcase and the locks (/etc/passwd.lock and /etc/group.lock) were removed.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

I don't know what jetty is, and I never installed it, it must have came with a package. I first noticed the terminal mentioning it after I installed node.js so I'm guessing node.js installed it. Looking it up, I see its a web server. I use apache2 so I have no reason to have jetty installed, I've been getting error messages every time I install a new application now, so I'm gonna try removing jetty.

Heres what happened when I tried to remove jetty:
