i have recently installed ubuntu 10.04. i tried to install few softwares it worked, then i got a problem and searched forums it said to delete the var/lib/dpkg/info(i guess). i did that and it worked. again now i'm not able to install softwares. i got the following error when i tried to update:

~$ sudo apt-get update
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the list directory


i again surfed nd found : :~$ sudo killall dpkg

but i got error: "dpkg: no process found"

what to do now?

Could you post the result of this command here:

priya@ubuntu:~$ ps ax | egrep 'apt|dpkg|deb'
4501 ? S 0:00 /usr/bin/python /usr/share/apt-xapian-index/update-apt-xapian-index-dbus
8872 pts/1 R+ 0:00 egrep --color=auto apt|dpkg|deb

If update manager is not running (or another package management utility), and it does not seem to be, you can remove apt lock:
but keep in mind that this can cause system issues so only do it if you are sure no package management application is running.

i tried update manager before trying the command u mentioned but i got a new error:
