Problems with installing of the openssh-server

[Forecaster]

Hi!

We installed 16.04 Ubuntu into LattePanda minicomputer (https://www.lattepanda.com/blog-tag/linux) and wanted to install ssh server for remote access.

What we received after our attempt to do it:
apt-get install openssh-server
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:
openssh-server : Depends: openssh-client (= 1:7.1p1-4)
Depends: openssh-sftp-server but it is not going to be installed
Recommends: ssh-import-id but it is not going to be installed E: Unable to correct problems, you have held broken packages.

Show your /etc/apt/sources.list. Also files in /etc/apt/sources.list.d if it's not empty.

Thank you about your good answer. I will do it at Monday. I worked all day today with Ubuntu and LattePanda.

Thank you!
This difficult task is fully solved -

How it was solved?
I have used this web-page fpr solving difficult task:
Method 2: Use Aptitude Aptitude is an alternative of apt-get which you can use as a higher-level package manager. You can use it to try and install your package with it, instead of apt-get, but first you need to install aptitude.


Press simultaneously the Ctrl, Alt, and T keys on your keyboard to open a
Type in sudo apt-get install aptitude and press Enter to execute the command.
Type in sudo aptitude install PACKAGENAME, where PACKAGENAME is the package you’re installing, and press Enter to execute it. This will try to install the package via aptitude instead of apt-get, which should potentially fix the unmet dependencies issue.

Serge
