hi,
i am a new user in linux.I just tried to install g++ in my laptop from command prompt.i Use this code

qvantel@qvantel-laptop:~$ sudo apt-get install g++
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?
qvantel@qvantel-laptop:~$

and got the above error.Please tell me what to do.

Sounds like the error you get if the GUI package manager is open while you try to use the command line package manager.

If you really want to use the command line package manager (apt-get) then make sure the GUI package manager is closed.

But you may be better off finding g++ in the GUI package manager and getting it that way.

then tell me how to install g++

'sudo apt-get install g++' will do.

But you will have to wait until the "Automatic check for updates"
has finished. And of course close all 'GUI package install' tools,
as said by @johnsfine.

Or use 'Synaptic' or 'Ubuntu Software center' for the install.

..

hI,

thanks for your replay.But i think i got the problem.Actually previously i installed sunjava through apt-get install
sun java6.0.Which is installed successfully and i am able to use it.but at end of the installation it is opening a gui prompt of java.As i am doing from command prompt i am not able to close it.So even if i am closing the terminal the process still exit.So,next time when i am doing any apt-get install g++ it is not allowing.I clean up the apt-get lock but after that whenever i trying to install anything through apt-get it is upgrading the java file again and stopping at same point. Is there any way i can solve it.if not i think i need to uninstall the java application and then try to install g++.


can u suggest as per the suitability.

Hopefully someone else can give you better details than what I recall. But in case waiting for a better answer is slow:

I have seen this problem using Synaptic, which doesn't look exactly the same but is the same underlying issue.

Installing Sun Java from the package manager is not self contained. During the install it tells you to get some additional file directly from Sun (I guess Oracle now). After you get that file, you can make the install complete. Until you have done that, every other install operation re reports the problem.

With Synaptic, I have had no trouble skipping over the problem, so other packages (G++ etc.) can be installed while the Java install is still unfinished. Also I have no trouble closing the failure in Synaptic leaving it unsolved (but not leaving it locked). Apparently closing it unsolved by not locked was not obvious using apt-get instead of Synaptic.
