cant check upates

[louis.roux]

I upgraded to the 10.10 and now I get a red triangle with a explanation point in the middle on the upper right hand of my screen next to the time and date. It apparently has to do with the update manager because when I click on it, it opens up the update manager. But when I try to install the updates I get the following message:


Failed to lock the package manager

Check if you are currently running another software management tool, e.g. Synaptic or aptitude. Only one tool is allowed to make changes at a time.

[zvacet]

As another way to update close update manager and type in terminal


sudo apt-get update && sudo apt-get upgrade

[Dutch70]

That usually happens when you have more than one of these three opened.

Synaptic Package Manager
Software Center
or the Terminal

[louis.roux]

@ zvacet: I did that but the following comes up in the terminal


owner@ubuntu:~$ sudo apt-get update && sudo apt-get upgrade
[sudo] password for owner:
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
owner@ubuntu:~$

@ Dutch70: I do not have more then one of those open. In fact I have rebooted my computer several times to see if I could get it to work.

That probably means that the mirror you're getting your updates from is currently down. Either wait a while or choose a different mirror.

[louis.roux]

What is a mirror and how do I choose another mirror?

[Frogs Hair]

The mirror is the location your download is coming from. To change it try Update manager settings > Ubuntu software tab and under download location choose other and a dialog box will open . Select use best server and Ubuntu will run tests to locate the best server . If you already have the best server try again later.

[louis.roux]

now I know I have a problem because when I run the test it says no suitable mirror found and tells me to check my internet connection. But my internet connection is just fine.

You need to disable the Cdrom as a source
deb cdrom:[Ubuntu 10.10 _Maverick Meerkat_ - Release i386 (20101007)]/ maverick main restricted in sources.list and un-tick all the non-maverick sources in Software Sources.

It might even be worth deleting them.

Then run
sudo apt-get update and post the result.

Good Luck

Still getting the following in terminal


E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
owner@ubuntu:~$

and the following when I try to install through the update manager
Failed to lock the package manager

C
heck if you are currently running another software management tool, e.g. Synaptic or aptitude. Only one tool is allowed to make changes at a time.

The package indexes are currently changed by apt-get.

[kagerato]

There's a discretionary lock on some of apt's key files. That means that more than one program is trying to access those files simultaneously. The second (third, etc.) programs will not proceed as long as they're designed to obey the discretionary lock, because doing so could cause substantial data corruption.

Essentially, you just need to close whatever application is holding the lock. It might be the software center, or the background updater, or Synaptic, or another apt-get process in a terminal somewhere. Check around.

[Dutch70]

You can check in system monitor. I'm not sure exactly what to tell you to look for though.

[plucky]

If you cannot find anything in system-monitor,try deleting the lock file.
Use
cd /var/lib/apt/lists/
sudo rm lock

Then run the "sudo apt-get update" command and it will be re-created.

Good Luck

[louis.roux]

Plucky that was the answer. thank you
