Ubuntu – Not able to configure SSH in Ubuntu 14.04 LTS

14.04software installationssh

I downloaded and installed Ubuntu 14.04 LTS on my VM and found that SSH was not working. Tried following but nothing worked:

sudo apt-get install ssh

I see only openssh_client installed, I don't see openssh_server not installed.

Can you help me to install openssh_client, i tried sudo apt-get install openssh-server
this gave following error:

Package openssh-server 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 'openssh-server' has no installation candidate"

Best Answer

I had the same problem it worked by following steps

sudo apt-get remove openssh-client
sudo apt-get update
sudo apt-get install openssh-server.

Some may think that removing ssh client will break everything, which is not true. It only removes ssh client app.

ssh issue appear to be there in all Ubuntu 14 Desktop versions, and this appear to be the easiest solution.

The official java packages has been removed from the Ubuntu repositories. You can install open-jdk instead:

sudo apt-get install openjdk-7-jdk

If you need the real thing you need to install the oracle java package:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Ubuntu – How to install latest Graphviz

I presume you are trying to install that package using sudo dpkg -i package, well, that normally leads to package dependency problems so normally I suggest the use of gdebi. If you have any problematic package remove it. You can check using sudo apt-get check. Now down to business:

sudo apt-get install gdebi-core

With that we have ready gdebi. Now if you use a 64-bit system you may like to install the 64-bit package, likewise with 32-bits.

Now here comes the funny stuff...

sudo gdebi graphviz_2.37.20140208.0545-1\~saucy_amd64.deb

This package is uninstallable
Dependency is not satisfiable: libgd2-noxpm (>= 2.0.36~rc1~dfsg)|libgd2-xpm (>= 2.0.36~rc1~dfsg)

And here is where you stop. The reason is that the stable package depends on package that were dropped of Debian, ergo Ubuntu 13.10:

libgd2 (2.0.36~rc1~dfsg-6.1) unstable; urgency=low

  * Non-maintainer upload.
  * Support multi-arch: (closes: #652496)
    - Mark libgd2-xpm, libgd2-noxpm, libgd2-xpm-dev and libgd2-noxpm-dev
      as same.
    - Adjust d-shlibs and dh-buildinfo build-dependency.
  * Drop .la files.

Those are dependencies of graphviz so they should change them to libgd2-xpm-dev and libgd2-noxpm-dev respectively. If that's the case, you should download the latest build instead 2.38 or later, which includes the correct dependencies.
