Raspberry Pi w/ OpenCPN

[Hakan]

Roberto..
I don't understand your fault messages but if you don't have the RPi for anything else and you have another PC for the SD card creation try a new SD card and set up Openplotter: https://openplotter.readthedocs.io/e...ing.html#basic

[verkerkbr]

If you dont' use OpenPlotter and like to install OpenCPN on a RPI it goes as follows:

sudo add-apt-repository ppapencpn/opencpn

There is a change that add-apt-repository is not available. then you most install this first:

sudo apt install software-properties-common

Then the add-apt-repository instruction again and see if it is working.

Update the system lists:

sudo apt update

And now you can do: sudo apt install opencpn.

That it.

Should be

sudo add-apt-repository ppa:opencpn/opencpn

The forum converts a colon followed by o to an emoticon if you don't wrap it in a "code" identifier.

Does this differ from instructions in the manual? If so, should yhe manual be changed?

Just tried the command above:-

$ sudo add-apt-repository ppa:opencpn/opencpn
Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 95, in <module>
    sp = SoftwareProperties(options=options)
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 109, in __init__
    self.reload_sourceslist()
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 599, in reload_sourceslist
    self.distro.get_sources(self.sourceslist)    
  File "/usr/lib/python3/dist-packages/aptsources/distro.py", line 93, in get_sources
    (self.id, self.codename))
aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template for Raspbian/buster

I'm looking for help to install OpenCPN on a Pi4.

What version of OS are you running ?

If it is a 64 bits version you can install the flatpak version, running in the flatpak enviroment (sandbox) Then the OpenCPN version is universal and not dependent of the OS version.

In the flatpak version all the plugins are available. Works on AMD 64 and ARM 64 bits versions.

If you are running Debian or Ubuntu then the OpenCPN software is allready in the repository.

Installing is very simple to do: sudo apt install opencpn.

I'm running the Rasp OS 32 bit that identifies itself as buster.

I'm not ready to try the 64 bit beta yet, so would prefer to install OpenCPN on buster.

Seems the information available relates either to stretch, bullseye or 64bit.

Here's the outcome of that:

$ sudo apt install opencpn
Reading package lists... Done
Building dependency tree       
Reading state information... Done
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

[verkerkbr]

The flatpak version is only working in 64 bits systems and as far as I know no efforts will be made
for 32 bits. You can install opencpn from the repository. If this is not working change the server adress to focal. Can easely be done in synaptic. Replace the name buster in the ppa server section to focal. Then update and try sudo apt install opencpn.

DickG...
I think we are all pretty confused about what version of rPI and OS you are running.
Please show the results of this:

$ uname -a
$ cat /etc/os-release

Thanks
Dave

Note that I recently tried changing "bionic" to "focal" - but the results were the same for both:-

$ cat /etc/apt/sources.list
deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
deb http:/ppa.launchpad.net/opencpn/opencpn/ubuntu focal main

1. Change the "focal" back to "bionic". Save the file.

2. $ sudo apt-get update
3. $ sudo apt install opencpn


Thanks
