I heard it is easy to install libraries on Ubuntu so I switched to Ubuntu, I tried to install boost so I write:
sudo apt-get install libboost-all-dev
and I get this:
Reading package lists... Done Building dependency tree Reading state information... Done 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: libboost-all-dev : Depends: libboost-python-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages.
Now I see that there is a canonical-question for this but as the answer suggests:
APT is a package management system for Debian and other Linux distributions based on it, such as Ubuntu. For the most part,APT is easy to use for installing, removing, and updating packages. In rare instances, often when you are mixing in third-party dependencies, there is a chance that apt-get may end up giving you an error telling you that a package installation could not be completed.
But I doubt there is anything rare about my situation. In fact the very reason I tried to install boost is because i know it should be a no-brainer, and i wished I would have some success with it before installing openscenegraph, which I will actually need. I wanted to try whether the basic things work, and it has let me down. please help instead of dupe-closing my question against the "general solution" I tried that, but at some point I have no Idea what the answerers are talking about i.e:
PPAs (Personal Package Archive) are repositories hosted on Launchpad. You can use PPAs to install or upgrade packages that are not available in the official Ubuntu repositories.
One of the most common causes of unmet dependencies are PPAs, specially when used to upgrade the existing package in Ubuntu repositories. To solve the problem you have tree options, disable, purge (revert back to original package in Ubuntu repositories) or remove PPA.
So my specific question is this:
I have installed Ubuntu 12.04 LTS this very day. I installed codeblocks, g++, build-essentials, no problem.
I tried to
sudo apt-get install openscenegraph, it may have worked although I cannot locate the header files on my hard drive(maybe I should have downloaded the
openscenegraph-dev(but it doesn't exist))
So I chose to install boost to see if this package installer works in the first place and I got(unmet dependencies) what I pasted above.
Why it doesn't work and how can I get it to work?
