Instruction to install OpenCPN on RPI3 does not work!

[reinM]

I tried to install opencpn on my rpi3 following the instructions in the manual.
Made a new Raspbian installation on a 16gb sd card. Following the instructions gives an error dirmngr does not exist.!
What is wrong ? Who has a solution ?

I know and I have OpenPlotter working, but I want to test if there is a difference in performance. Sometimes I don’t need the extra things from OP.

Don't know what's wrong, but solution is easy

sudo aptitude install dirmngr

Beste Rein,

the best result you get from OpenPlotter is an update to Linux Stretch and then switch on the VC4 driver. Then you get an excellent performance of OpenCPN on the Raspberry Pi3.

OpenPlotter is working on a Linux Stretch version (Debian 9).

But you can do it also yourselves. The instructions to do the upgrade is very simple.

Groet,

Bram

Tried loading htop? "Sudo apt-get install htop" , the just "htop" to start the program which will show what resources each process is using. You can kill processes one by one to see what changes. Openplotter processes are typically well below 10%.

I still tried on a new loaded sd card to get openCPN without Openplotter, I did :

sudo aptitude install dirmngr

Followed the instructions on OpenCPN Raspbian 2/3

after

sudo apt-get install opencpn

I get as result :

Pakketlijsten worden ingelezen... Klaar
Boom van vereisten wordt opgebouwd
De statusinformatie wordt gelezen... Klaar
Sommige pakketten konden niet geïnstalleerd worden. Dit kan betekenen
dat u om een onmogelijke situatie gevraagd heeft, of, indien u
de distributie 'unstable' gebruikt, dat sommige benodigde pakketten nog gemaakt moeten worden of uit 'Incoming' verwijderd werden.
De volgende informatie kan misschien helpen de situatie op te lossen:

De volgende pakketten hebben niet-voldane vereisten:
opencpn : Vereisten: libtinyxml2.6.2 maar het is niet installeerbaar
Vereisten: libwxbase3.0-0 (>= 3.0.0) maar het is niet installeerbaar
Vereisten: libwxgtk3.0-0 (>= 3.0.0) maar het is niet installeerbaar
Aanbevelingen: xcalib maar het zal niet geïnstalleerd worden
Aanbevelingen: opencpn-doc maar het zal niet geïnstalleerd worden
Aanbevelingen: opencpn-gshhs-intermediate maar het zal niet geïnstalleerd worden
Aanbevelingen: opencpn-gshhs-high maar het zal niet geïnstalleerd worden
Aanbevelingen: opencpn-gshhs-full maar het zal niet geïnstalleerd worden
E: Kan problemen niet verhelpen, u houdt defecte pakketten vast.

Anyway, Merry Christmas.

Beste Rein,

you must have the correct server settings to install OpenCPN.

What is wrong with OpenPlotter ? You can switched off the items you don't like.

My recommandation is: OpenPlotter 0.10 with the latest updates. Linux and the latest updates sudo apt update en sudo apt upgrade. Latest kernel update sudo rpi-update. Now 4.9.70.

And then changing the server settings from jessie to stretch.

sudo apt update en sudo apt upgrade. It is a very large update, but simple to do.

Then remove all the unused files with sudo apt autoremove.

To speed things up: sudo raspi-config en switch vc4 driver to on.

Groet,

Bram
Have a nice weekend.

Rein...
Would it be possible to do us a favour and run the commands with english locale while intending to post their output here? Like in

LANG=C apt-get install opencpn

Anyway, your Raspbian repositories do not contain packages able to satisfy OpenCPN's dependencies. libtinyxml seems to be renamed to libtinyxml2.6.2v5 and all the wxWidgets packages have -0v5 suffix added to the name in Debian Stretch, on which your Raspbian probaby is based.
This means only one thing, you can't use the packages for Ubuntu Trusty on Stretch based Raspbian anymore. But looking at the Ubuntu repositories, you might have luck using Xenial instead.

I really doubt you can get any measurable performance advantage over OpenPlotter doing this, but you are of course free to try.
