Introduction

Problem description

When trying to install a NavVis package via apt-get, apt prevents the installation, lists several dependencies, and tells me that these are “not going to be installed”. This means that at least one of the dependencies cannot be installed. Often the dependencies of dependencies have conflicting versions.

Scope

This solution applies to NavVis M6 and NavVis VLX software.

Troubleshooting procedure

Solution 1

  1. Make sure your system is up to date. Check which packages are missing. You can check the dependency graph by recursively running:  

    apt-get install

  2. To update, try the following: 

    sudo apt-get update

sudo apt-get dist-upgrade

  3. This should update your dependencies, and you should now be able to install your package(s).

Solution 2

If this does not work or the trolley software does not run smoothly after that, you can purge all NavVis software and ROS packages on it and re-install:

  1. Purge the current NavVis software from the device or workstation:

    sudo apt-get purge 'navvis-.*' '^ros-.*'

  2. Add the following stable repos in /etc/apt/sources.list.d/navvis.list:

    sudo nano /etc/apt/sources.list.d/navvis.list

    These should go in there as an example (NavVis M6 stable release):

    deb http://repo.navvis.com/repo/navvis-stable/ bionic non-free

  3. Install the navvis packages from scratch:

    sudo apt-get update
sudo apt-get install navvis-repos
 
sudo apt-get update
sudo apt-get install navvis-trolley-m6  # or package "navvis-trolley-m3"/"navvis-vlx" for trolleys, "navvis-desktop-full" for workstations

Solution 3

If none of the above helps, this indicates that there are some dependencies conflicts with Ubuntu.

  1. Navigate to Software & Updates from the All Applications menu.

  2. Go to the Updates tab and check all the checkboxes. If they were already checked, this solution will not work.

  3. Finalize with:

    sudo apt-get update

sudo apt-get install navvis-desktop-full
