Updating Mate Problems

[sarian90]

Hi

I have just replaced Raspbian Jesse with Ubuntu Mate on my Raspberi Pi 3, as I am running Ubuntu 16.04 on my main computer and I want to work with something I am familiar with.

I wanted to add some arduino software which requires doing a simple update and then install of the software as follows. I do sudo apt-get update and then sudo apt-get install arduino.

It comes up with the following 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?

If you have any ideas I would greatly appreciate it?

Kind Regards

Ian

Hi sarian90

This usually means that you already have a package manager open. Only one package manager can be opened at a time. or…

Sometimes dpkg will hang up and its necessary to manually remove the lock. In terminal:

sudo rm /var/lib/dpkg/lock

Hi @sarian90,

this is usually caused by the update manager running as soon as you start the system, it can take a few minutes for the updater to finish, especially if it is downloading security updates in the background!.

Hi

I tried the sudo rm /var/lib/dpkg/lock command and then tried an update but that didn't work.

I received the following errors:

I tried the initial command and then tried to install the arduino software and that went through ok.

So I still appear to have some issue there thats preventing the updating.

Is it possible to stop the update manager from updating initially?

Just remove it from the startup Applications I guess.

Hi

As a newbie to this, could you advise me where to find that to remove it?

Hi @sarian90,

before you remove anything from startup (Control Centre > Personal > Startup Applications), try changing your software sources download location per the update guide linked above!.
