Could not open lock file /var/lib/dpkg/lock

you may need to remove the lockfile

sudo rm /var/lib/dpkg/lock

Negative...says

cannot remove '/var/lib/dpkg/': Is a directory

Please give us which command you are typing...

Thank you

Well, I've tired to install Beagle (apt-get install beagle); VLC ( apt-get install vlc )

so I guess the command is the (apt-get install).

You must use sudo to give administration commands to Ubuntu...

Play mp3 and dvd under Ubuntu

First please install https://help.ubuntu.com/community/RestrictedFormats

You need to have extra repositories enabled..

Please first enable the multiverse repository:

Open System → Administration → Software sources → [ Tab Ubuntu software ]
enable "Software restrictecd by copyright or legal issue ( multiverse )"
Close and confirm the repository reload.

Type the following command in a terminal (applications → accessories → terminal)

sudo aptitude install vlc

To get better dvd playback first you need to add the medibuntu http://www.medibuntu.org/ repository to your /etc/apt/sources.list file:
here howto add https://help.ubuntu.com/community/Medibuntu here the medibuntu available software list http://packages.medibuntu.org/

Then to install:

sudo apt-get update
sudo aptitude install libdvdread3 libdvdnav4 libdvdcss2
sudo aptitude install non-free-codecs gstreamer0.10-pitfdll w32codecs ubuntu-restricted-extras

give your user password when requested, you don't see nothing when you type it, then press enter.

Hope this helps

I got as far as:

sudo aptitude install libdvdread3 libdvdnav4 libdvdcss2

and I get this:

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?

You must run only one package manager a time, please close Synaptic or other packager manager opened...

To be sure no other package manager is opened you can also reboot your pc...

Thank you

Ok, rebooted my machine and now get the following:
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

when I run

sudo aptitude install libdvdread3 libdvdnav4 libdvdcss2.

Sorry I'm still learning. Thank you for all your help in this matter...

Open a Terminal from the menu Applications → Accessories → Terminal and type:
(when the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove

Hope this helps

Then go on with your install commands

sudo aptitude install libdvdread3 libdvdnav4 libdvdcss2

Hope this helps

ok, go to:

sudo apt-get --fix-missing install
and it then says:

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?

when I put in the (sudo apt-get -f install) the terminal turns blue and
there is a java statment.

How do I end a process?

Restarted the computer several times and finally the above worked. Thank you for you help on this.

Whene the pc start it run a check for available updates so into the first minutes might be it try to fetch repository index and you will not able to run any other packages manager...

More settings you will find under System → Administration → Sofware sources [ updates ] tab...

Hope this helps

I recently encountered a similar problem when trying to install the program. To solve this problem, I introduced a single command: $ sudo!! Then put sudo apt-get install easytag and I have everything worked as before. I do not see much in the process, but it helped me. I hope this helps you too!
