Random getpwuid_r(): failed due to unknown user id (0)

Post by antimatter » Tue Nov 08, 2011 9:45 am

Hello,
I’m sorry for starting another discussion about this bug, but as the other discussions context do not match, it felt legitimate to start a new one.

As the thread title already mentions, I am getting this error message a lot lately. But it doesn’t happen during boot, shutdown, awakening from or suspend to disk. The system is always up and running for a while (30+ minutes) and in the middle of my work the screen goes black and on top there’s this message:

GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)

There’s also a process id included at the front, but this is always different.
My user id is 1000. I checked by issuing the ‘id’ command.

This problem is quite serious for me, because the following does not work, when the error occurs:
— Ctrl+Alt+Backspace
— Ctrl+Alt+Del
— Ctrl+Alt+Fx
— Ctrl+C
— Alt+F4
— Any other shortcut, I can remember

Mouse freezes too. The only thing I can do is forcing the machine to turn off by holding the power button pressed.
This problem happens once or twice a weed the machine wasn’t doing any exotic operations. I was reading a document, surfing the web or nothing at all (idle).
The machine is a HP Probook laptop, model 6450b. I’m running Mint 10 64-bit.
I switched to Mint in March this year and reinstalled it a few weeks ago. Before the reinstall, which I didn’t do any different compared to March, I never had this problem.

Any help will be much appreciated. If you need further information about the system, just ask.

unable to chown a directory recursiverly «unknown user id»

I trying to chown the directory for changing the permissions of the directory. But it shows some error as unknown user id I tried to chown using the command : chown -R www-data [directory name] it shows the error as unknown user id www-data How to get rid of this.

I’m guessing you’re using a guide for a Debian-based distro which has a www-data user, except you’re trying to use the guide on a distro that doesn’t have that user. Please point to the guide and tell us what distro you’re using.

yes, you are true. I’m using Debian-based distro, actually this problem occurred in webdesigning in drupal. I couldn’t get write permissions for a directory.

If you’re using a Debian-based distro, you should have a www-data user. I’d figure out why you don’t.

1 Answer 1

Your problem is simple, that user/id doesn’t exist:

$ chown adsfadsf files chown: invalid user: ‘adsfadsf’ 

Verify the user exist and try again.

Exactly. If you wade through the huge number of posts in the Ubuntu forums that are referenced in a Google search, there is a patch that will supposedly fix the warning message.

It’s non-critical and hasn’t caused any issues for either of the editions I build here, or for Pepeprmint. Remember that it’s just a warning, and warnings don’t mean anything is «wrong» per se. From my early looking, it appears the warning is present in the 11.04 builds as well.

So are the packages used in LMDE more stable then the ones in Ubuntu based Mint? because I thought the packages were from the Romeo repository & so things were the other way around?

I believe most of your LMDE packages (if not all of them) come from debian repositories. I havn’t used LMDE in a while but that was how it was when I did

Forcing the install of the latest version of plymouth for ubuntu solved the issue for at least one mint user:
http://forums.linuxmint.com/viewtopic.php?f=90&t=64980

I haven’t done it because it simply slows down the recovery from sleep and has never caused a reboot or freeze, and I’m afraid forcing the install of ubuntu’s plymouth version might have unintended consequences.

Same issue here. I am using:

Julia
Samsung N210 — Intel GMA 3150.

The message can be seen during shutdown and when resume from suspend. I was so annoyed that I clean reinstalled 3 times (from Live USB) and burnt it ‘fresh’ on USB everytime through unetbootin — Still no luck.

It seems the warning message doesn’t affect some people though. And sudo dpkg-reconfigure plymouth didn’t seem to do anything either.

Must be someone out there who knows what is going on?

It’s a bug in the Plymouth boot splash (the Linux Mint logo during boot). You can disable Plymouth by replacing ‘splash’ with ‘nosplash’ in /etc/default/grub in the CMDLINE_LINUX_DEFAULT line, and then turning off splash in Startup Manager (somewhere in the menu). You will get a boot screen without Mint logo, just some text you possibly won’t understand, but it works.

Thanks a lot. It did solve the problem. What I did was just to remove ‘quiet splash’ as this is = ‘nosplash’. The Glib warning is no longer there. I wonder if there is an update for linux mint. As I understood it, the Ubuntu users have similar issues, and a fix update has been released, here > https://launchpad.net/ubuntu/+source/pl . 2ubuntu5.1

I am tempted to apply that update but don’t want to end up having Ubuntu splash screen.

You won’t get an Ubuntu screen: the screen is not in the ‘plymouth’ package but in a seperate one, which does not get changed with the fix you gave.

Does anyone know if this error has been spotted in the Release Candidate Linux Mint 11?
