opencpn on Ubuntu 17.04

[titaantje]

I tried to install OCPN on Ubuntu 17.04.
As suggested on the download page of OpenCPN I tried to add ppapencpn/opencpn by issuing the commands:
sudo add-apt-repository ppapencpn/opencpn
sudo apt-get update

but, although the ppa seems to be added, OpenCPN does not launch.
I can't figure out why.
Does anyone have any suggentions?

The add-apt-repository step informs your package manager about additional place (repository) to look for software.

The update step makes your package manager refresh its knowledge about _available_ software in all repositories it knows about. In and of itself this step does NOT install any software.

To install OpenCPN (or any other available software package) you need to tell your package manager to do so. Likely this will do:

sudo apt-get install opencpn

Once this step is done, typing opencpn on command line should launch OpenCPN.

$ sudo apt-get install opencpn

Package opencpn 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 'opencpn' has no installation candidate


Not yet solved, but perhaps this reveals a clue??

I haven't had much luck with adding repositories with the PPA.... Might want to try downloading the source code to install that way.

It always worked for me (as well as installing from source when I wanted to play with it a bit). It seems that it is time for one of package maintainers to step in and verify there is a Ubuntu 17.04 opencpn package in the repository.
The official manual https://opencpn.org/wiki/dokuwiki/do...ion:ubuntu_ppa offers no further clues either.

It seems like the packages are where they should be
Index of /opencpn/opencpn/ubuntu/pool/main/o/opencpn
but I have no time to investigate further. One more suggestion is to move to Ubuntu 16.04 which is a LTS release with 5 years of support, while 17.04 is an interim release with only 9 months of planned support. I tend to keep to LTS releases for production / mission critical uses.

It is a matter of installing the right server adress.

If you have synactic. If not install it by:

sudo apt install synatic.

start Synatic
go to settings
package sources
go to ppa (not always needed)

add server address

deb http://ppa.launcpad.net/opencpn/opencpn/ubuntu xenial (or trusty) main

then reload

in find you may see opencpn

but take the terminal after closing Synaptic

sudo apt update
sudo atp upgrade

you get an error message, but pass it.

And OpenCPN install on your system.

Thanks for tour reply.
I managed to install OpenCPN by compiling from source.
I read Brams reply after finishing the compiling. It's a pity, that would have been a lot easier.

What Bram suggested was a way to instruct package manager to use opencpn package compiled for an earlier distribution of Ubuntu. It may work or not, depending e.g. on libraries compatibility.

Comparing the PPA package lists for Xenial and Zeisty:
http://ppa.launchpad.net/opencpn/ope...64/Packages.gz
http://ppa.launchpad.net/opencpn/ope...64/Packages.gz
one can see that opencpn package is present in both, although there are fewer opencpn companion packages (plugins, etc.) compiled for Zeisty at the moment, so it may be a matter of waiting a few days till the PPA is fully updated.

All...

We have updated the OpenCPN PPA with OpenCPN 4.6.2 for Ubuntu 17.04 (Zesty).

Normally we only update the PPA for new LTS Ubuntu releases.

However, in this case we have done this update as a convenience for those wanting to use OpenCPN with the latest Ubuntu release.

Good Luck

I think there is a problem with the packages opencpn-tcdata et opencpn-gshhs-low. It appears several times with the name utopic in your repository ppa and never with the name xenial or zeisty.

There is an error when you want to install opencpn package :
opencpn-tcdata which is a virtual package and is not provided by any available package
opencpn-gshhs-low which is a virtual package and is not provided by any available package

Hi,
I have just tried to install opencpn on ubuntu 17.04 by referring to the PPA but unfortunately all dependency packages (opencpn-tcdata, opencpn-gshhs-low, ...) are unavailable.
Any ideahow to fix this? I would like to avoid to compile it myself.

Kind regards

[Hermione]

Same for me, opencpn download page should telling that only LTS versions of ubuntu is suported.

@fodiator,
@Hermione,

Folks, in post http://www.cruisersforum.com/forums/...ml#post2389951 Dave explained, that a compiled version for 17.04. is just a convenience measure for non-LTS Ubuntu users.

The missing packages are just data packages for OpenCPN, so try to get a package compiled for a previous LTS release and just install it manually. It should work.

The compiled packages are here:
Index of /opencpn/opencpn/ubuntu/pool/main/o

To install e.g. opencpn-tcdata download the .deb file and then install it from a command line with:
dpkg -i opencpn-tcdata_3.3.2107-0~utopic1_all.deb
