If you are getting the following error when you try to install any packages use the following tip to fix this

Error

E: Could not get lock /var/lib/dpkg/lock -- open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Solution

First thing you need to check Synaptic Package Manager open at the same time

or

That happens when synaptic or another package update / installation application is already running. Close any other package managers (including Add/Remove application, language pack installer, etc.) and retry.

    I’ve actually found that recently my apt-get isn’t closing cleanly either, so that it keeps running even if I close the terminal window. A quick “sudo killall apt-get” fixes that, although I’m guessing that this isn’t most proper way of doing things.

    I’m unable to find anything running, system monitor says everything is sleeping. I even ran sudo killall for apt-get and synaptic and it says “apt-get: no process killed” etc. In the mean time I can’t update my 7.04 alpha system, it says run “dpkg –configure -a”. I ran it but don’t know what to do when it opens. var/lib/dpkg/lock with white X in brown box in the upper right corner, 0 bytes. Help me Ubuntu Geek, your my only hope.

    Some packages could not be installed. This may mean that you have
    requested an impossible situation or if you are using the unstable
    distribution that some required packages have not yet been created
    or been moved out of Incoming.

    Since you only requested a single operation it is extremely likely that
    the package is simply not installable and a bug report against
    that package should be filed.

  14. Lindsay says:

    I “was” also having the lock problem; but I was trying to purge and install a package using a ruby script started by a Webmin Cluster Cron Job.

    Anyway … the problem was the placement of the -y(es) switch. These work, putting the -y any where else FAILS with the lock problem.

    apt-get –purge remove -y mediawiki
    apt-get -y install mediawiki

    Hi,

    I encountered the same problem before, I accidentally close the terminal and tried to issue the same command (apt-get install kubuntu-kde4-desktop) and encountered the said error. Maybe we forgot the basic, I issued ps ax and simply kill the running process of apt-get and my problem solved!

    Hope this helps…

    When you run sudo apt-get update
