can not install ,update packages

Hi There,

I suspect that your problem is that you have too many 'installation' programs open. You can run EITHER synaptic or apt-get or Add/Remove Programs, but not all concurrently.

Please can you try just running one of the options and tell us if this solves your problem?

I did, but still the same:-(

Hi (again!)

Have you tried by just clicking the icon on your task-bar (in the top-right corner) that looks like a white asterisk on an orange square? That is the update notifier, so if that is 'doing something', the other methods will not work.

Can you try closing synaptic and your terminal and selecting the icon mentioned above, to see if that works?

Still the same, and i put the mouse pointer(?) on it,it gives a small window saying the error message as above.I clicked that, and the updater window came but immediately disappeared.

You actually have two problems, one has been explained - you can only run one update application at a time. This will fix this error message:-

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?

However the second problem is that the file /etc/apt/sources.list.d/edgy-universe.list is corrupted in some way.

In your screenshot you showed us /etc/apt/sources.list when you should have shown us /etc/apt/sources.list.d/edgy-universe.list

Please check that file, and if necessary post it here for us to fix.

Here is the screenshot:

Thank you so much for your continuous help, and thanks a million in advance!!!

You already have edgy-security listed in /etc/apt/sources.list, so you don't need it in /etc/apt/sources.d/edgy-universe.list too. I would move or remove that file.

$ sudo mv /etc/apt/sources.list.d/edgy-universe.list ~

To move it to your home directory. Then try apt-get again.

It looks like there is a / missing after the ubuntu on the second line. If you run

sudo gedit /etc/apt/sources.list.d/edgy-universe.list

and change the second line from

deb http://security.ubuntu.com/ubuntu edgy-security

to

deb http://security.ubuntu.com/ubuntu/ edgy-security

Save, close, and try an update again?

i had the same problem as above the same command solved the problem:

         sudo mv /etc/apt/sources.list.d/edgy-universe.list ~

Wonderful good post :)
