I would like to install the gpointing-device-settings package which I found on the Launchpad website    I tried:  apt-get install gpointing-device-settings   but I get the following reply:  E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?   I also tried  add-apt-repository ppa:gpointing-device-settings   and got  Error: must run as priviledged user   Can anyone point me in the right direction please as I seem to have got my brain into a loop...

Last night I was updating my Ubuntu 10.04 to either 11.04 or 12.04 (I'm not entirely sure which one it was, but I think it was 11.04) and I left it overnight to finish. When I came down in the morning, I noticed that the computer hadn't barely begun installing the updates! The update thing said that my computer was on the installation step, but it was still preparing the libc bin (or whatever its called) . It's like the first part of the step installing the upgrades. So, I stupidly restarted the computer, and when it rebooted, I got five options on a purple screen:  Ubuntu, with Linux 3.0.0-28-generic Ubuntu, with Linux 3.0.0-28-generic (recovery mode) Previous Linux versions Memory test (memtest86+) Memory test (memtest86+, serial console 115200)   Long story short, not matter which way I enter Ubuntu to try and reinstall the updates using the root thing (it's like terminal) after I enter sudo apt-get update it basically said it failed to fetch every url link, and it then says:  W: Some index files have failed to download. They have been ignored, or old ones used instead. W: Not using locking for read only lock file /var/lib/dpkg/lock E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.   So, I entered sudo dpkg --configure -a, and it says:  dpkg: error: unable to access dpkg status area: Read-only file system"   I'm left like wtf, and I really just some guidance here. I just got this laptop, and I can not afford a new one if I broke this one.

Hi everyone I'm attempting to install spotify, I've been running linux for less than 24 hours so please cut me some slack if this seems trivial. Here is a link to the webpage  and the example script.         Add this line to your list of repositories by editing your /etc/apt/sources.list    deb http://repository.spotify.com stable non-free    If you want to verify the downloaded packages, you will need to add our public key  sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 94558F59    Run apt-get update  sudo apt-get update    Install spotify!      sudo apt-get install spotify-client      would someone be nice enough to walk me through this? I'm not even sure where to start.

PPA seems to be constantly offline. Whenever I use sudo apt-get update, this error is shown:  W: Failed to fetch http://ppa.launchpad.net/ 404  Not Found   How do I fix these errors?

is a fantastic repository of packages, and one that I use often to install packages that are not included in the main repository. Thus far, I've always simply browsed to a package page (e.g. ) and manually downloaded the Deb file, which kicks off the Ubuntu Software Center and lets me easily install the package.  It would be even cooler if I could use LaunchPad.net as a regular apt source, i.e. by doing something like this:  echo 'deb https://launchpad.net/ubuntu natty amd64' | sudo tee -a /etc/apt/sources.list   Does anyone know what the correct sources line would be?

After a reinstall of Ubuntu 12.04 ,it's impossible to install commercial games, e.g Oil Rush. It gives this error:  Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/oilrush/ubuntu/dists/oneiric/main/binary-amd64/Packages  The requested URL returned error: 401 Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/oilrush/ubuntu/dists/oneiric/main/binary-i386/Packages  The requested URL returned error: 401 Some index files failed to download. They have been ignored, or old ones used instead.   I bought these games in 11.10, but I installed these games in 12.04 before... How can I solve this problem?

I did a few quick google searches, and it looks like the most recent  about this was back in 2012.   How might I go about disabling mouse acceleration in Ubuntu 15.10? I tried installing gpointing-device-settings but there were many errors.  I'm looking for a persistent setting.

I am getting error while using sudo apt-get upgrade stating:  dpkg: error processing libgfortran3:amd64 (--configure):   package libgfortran3:amd64 is not ready for configuration   cannot configure (current status `half-installed') Errors were encountered while processing:   libgfortran3:amd64 E: Sub-process /usr/bin/dpkg returned an error code (1)   It does not seem to block the installation/upgrade other applications. I believe this problem arose due to direct shutting down of my PC while the application was being upgraded.  How can I fix this?

I have no way of accessing any of my settings on my fresh install of Ubuntu 17.10.  I installed 15 minutes ago, added a few core packages, one of which was wine where dpkg failed and I had to restart it.  And it keeps telling me randomly that an install failed of : libsane1 (experimental).  After I installed those packages, no settings available.  The menus are gone, their icons are gone, they won't load even if they have an icon.    As soon as I got the first error message from dpkg, I did a   sudo apt-get remove libsane1   which went perfectly well and appeared to clear up the error.  Then back and did a   sudo apt-get install libsane1   which also went perfectly fine and no problems seemed to exist.  Only during the installation of wine-hq-staging on my fresh and clean ubuntu does the error appear.  Well it also appears on winehq-stable too but I did not use that this occasion.

This question always bothers me! Last time for 4.9 I tried the commands mentioned in . The same trick doesn't work now:  sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt-get update sudo apt-get install gcc-5.1 g++-5.1   results in...  E: Unable to locate package gcc-5.1 E: Couldn't find any package by regex 'gcc-5.1' E: Unable to locate package g++-5.1 E: Couldn't find any package by regex 'g++-5.1'   What is the correct command for directly installing the latest g++ in Ubuntu? Is there any magic command which works uniformly for all the updates of g++?  Update:  I found that the correct command to install it is:  sudo apt-get install g++-5   This works now! Though in the , the version is 5.1.

Mainly I am looking for a way to pin an application to the Unity launch bar, and run it as root.  Currently, even if I start the application with sudo, and pin it after it starts, it will start as current user next time.  Sad, but there is no context menu option "run as ...".  Update: I switched to gnome3 and now I'm happy, I'm missing only the search.

I installed  (Precise Pangolin), 64 bit. Nowhere was I asked to set password for root.  I just installed  software. It was installed under the /root folder by default. Now I try do something on that folder. I tried with su to switch to root, but I don't know its password.   Should I always use sudo or get the default root password, if any?  How do I create a  for software installed inside the /root directory?
