14.04.2 LTS Live/Install DVD: openssh-server can not be installed from DVD directly

Asked by Maddes

It is not possible to install the OpenSSH server directly from the current Desktop/Live DVD 14.04.2 LTS (Trusty Tahr) due to unmet dependencies.

I would be great to install an OpenSSH server without needing any internet access to the repositories.
My machine is build inside a very small compartment, so accessing the machine physically is extremly uncomfortable, so getting remote access to it as fast as possible is preferable.

Could you please add this to your quality checks for upcoming Desktop/Live DVDs. Thanks.

Is there a workaround for the current situation?

You could remaster the Ubuntu ISO to have it by default

Please provide the exact name of the .iso file that you are using.

As a workaround maybe you could try to use the command

apt-get install --reinstall --no-install-recommends openssh-server openssh-client=1:6.6p1-2ubuntu1

@actionparsnip:
I'm just a user, but if you can guide me to a HowTo for remastering the Desktop/Live DVD, then I would have a look.

The ISO was downloaded several days ago from ubuntu.com: ubuntu-14.04.2-desktop-amd64.iso

I tried several combinations of --ignore-hold, --no-install-recommends, --fix-broken, --ignore-missing and --reinstall but to no avail.
Therefore I investigated further:
* openssh-client is "installed" in ISO, but openssh-server is not, which is ok.
* The already installed openssh-client (ubuntu2) is newer than what the openssh-server needs (ubuntu1) according to the apt lists from the Live CD.
* The package openssh-server seems to be not present in the ISO (searched /pool for it). So right now an internet connection is required to install openssh-serve at all.
* My wish would be to have the matching openssh-server package available in the ISO. This way an easy and fast remote access would be possible without the need of an internet connection.

Can anyone confirm my findings and assumptions?
Should I file this as a "bug"? If so, for what package?

Are you installing a desktop system or a server?

As far as I can see, the openssh-server package is available in the ubuntu-14.04.2-server-amd64.iso installation kit.
So installing your system from the server .iso should have worked.

I use the Desktop ISO on an USB stick as a Live System when needed.
(On that specific machine I installed a (remote) desktop system. )

I will try the server ISO as a Live System and see if that works.

The server ISO cannot be used as a Live system, therefore this was not the solution.
Will file a feature "bug" and hope the next Desktop/Live CDs come with an OpenSSH server installed or at least package included for installation.

I do not understand why you would expect an openssh-SERVER package to be available on a desktop live system.
If you have connection to an Ubuntu package repository, it is available anyhow.

Can you help with this problem?
