I need to install the package ffmpeg because I am trying to install subsonic server on my new Ubuntu Gnome 14.04  When I try:    apt-get install ffmpeg    I get:  Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:  The following packages have unmet dependencies:  ffmpeg : Depends: libavcodec54 (&gt;= 7:1.2.5~) but it is not going to be installed or                    libavcodec-extra-54 (&gt;= 7:1.2.5~) but it is not going to be installed           Depends: libavdevice53 (&gt;= 7:1.2.5~) but it is not going to be installed           Depends: libavfilter3 (&gt;= 7:1.2.5~) but it is not going to be installed           Depends: libavformat54 (&gt;= 7:1.2.5~) but it is not going to be installed E: Unable to correct problems, you have held broken packages.   I have tried apt-get -f install ffmpeg apt-get install --fix-broken apt-get autoclean apt-get autoremove    With no luck at all. I found a repository and added it to my sources via: add-apt-repository ppa:jon-severinsson/ffmpeg  With still no luck.  I found this question   which led me to try this:    apt-get install libav-tools    which resulted in this:  Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:  The following packages have unmet dependencies:  libav-tools : Depends: ffmpeg (&gt;= 7:0.10~) but it is not going to be installed E: Unable to correct problems, you have held broken packages.   I also have made sure my "Software &amp; Updates" have all the proper repositiories checked off, namely all 4 on the "Ubuntu Software" tab, and all on the "Other Software" tab with the exception of the second one (Canonical Partners Source Code).  I also have these checked off as well per instructions supplied on the page they lead to: http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu saucy main http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu trusty main  None of this works.  How can I install ffmpeg? Or if I cannot install it, what do I need to install to replace its functionality?

I tried to install ffmpeg in trusty/Ubuntu 14.04 and got the following message:  $sudo apt-get install ffmpeg  Reading package lists... Done Building dependency tree        Reading state information... Done Package ffmpeg is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source  E: Package 'ffmpeg' has no installation candidate   Why isn't the package available?

It is not unusual for an Ubuntu (or other distro with apt package management) user to encounter the error: user@box ~ $ sudo apt install x [sudo] password for user:  Reading package lists... Done Building dependency tree        Reading state information... Done Package x is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source  E: Package 'x' has no installation candidate  There have been several questions asked concerning this on various StackExchange sites,for example  on AskUbuntu, but these are generally about how to obtain the specific package despite the error. I have found no package that is not found simply (though not always easily) by determining if it is still distributed, and under which repository if so, and ensuring that repository is in apt.sources, or the worst comes to the worst downloading a .deb or source to compile. So my question is more general, and although I am guessing it has a rather simple and therefore non-exciting answer I cannot think how to find it by conventional search engine methods, so I turn to AskUbuntu: Is there a command or option I can use to determine what package / which packages reference the missing package?

I tried to watch a dvd and found that VLC was not installed. When I went to the Ubuntu software center I got this message when trying to install VLC. I do not know why. Here's the ouput:  "This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

I am trying to install gfortran in my computer with Ubuntu 12.04 by using these commands,  sudo -i apt-get update apt-get install gfortran   but I found the program saying "unable to locate package gfortran". Then on a Ubuntu page I found some question regarding the same problem and I went through the solution from them but again I couldn't install the gfortran package.  Can anybody tell me how to install it?

I have a deb package for installation.  Shall I install by dpkg -i my.deb, or by apt?  Will both handle the software dependency problem well?  If by apt, how can I install from the deb by apt?

After doing a man apt-get and cursory Google search it's not clear how I find new programs to install (from the internet) using apt-get (which is amazingly powerful and simple coming from another Linux distro).  I'm using Ubuntu Server 8.04 LTS (an inherited system used for some random work), so no GUI.  Anyone have quick advice here?
