Title:
Error installing software with apt and software center: /etc/passwd
locked by /usr/share/system-config-printer/applet.py
Status in system-config-printer package in Ubuntu:
Incomplete
Bug description:
Binary package hint: apt
I'm using Ubuntu 10.10. I tried installing Code::Blocks from the
Ubuntu Software Center and got a message "Package operation failed"
even though Code::Blocks seems to have installed perfectly. I've had
the same problem while installing other applications and have ignored
it without any repercussions that I can tell. Below is the output
when attempting the same installation from the terminal. The error is
identical to the one I got from the software center.
~$ sudo apt-get install libcodeblocks0

Setting up hal (0.5.14-0ubuntu6) ...
useradd: cannot lock /etc/passwd; try again later.
adduser: `/usr/sbin/useradd -d /var/run/hald -g haldaemon -s /bin/false -u
116 haldaemon' returned error code 1. Exiting.
dpkg: error processing hal (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
hal
E: Sub-process /usr/bin/dpkg returned an error code (1)
So I tried to see what has locked /etc/passwd and found the culprit is
applet.py:
greeenguru@Veronica:~$ lsof /etc/passwd
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
applet.py 1982 greeenguru 10r REG 8,1 1698 2886356 /etc/passwd
And I found which applet.py has locked /etc/passwd:
greeenguru@Veronica:~$ ps -Af | grep applet.py
1000 1982 1598 0 Dec20 ? 00:00:02 /usr/bin/python
/usr/share/system-config-printer/applet.py
It seems that /usr/share/system-config-printer/applet.py is locking
/etc/passwd, but I don't know how to solve this problem or even what applet.py
does. I found one solution on the forums:
http://ubuntuforums.org/showthread.php?p=9468367
but the solution is to run this:
sudo rm -f /etc/gshadow.lock /etc/shadow.lock /etc/passwd.lock
and I don't fully understand what the repercussions of that might be.
