With the NMEA Network connected to the pi I have GPS time and date via NMEA.
But how to set rpis time and date via this NMEA stream?

Now I do it manually after every shutdown with the "date" command.

Did not try because I have a RTC which is a good solution as well.

keep coming up with the same result using a raspberry Pi4b, have several rapberry pi3 B+ with OpenCPN V4.8.8 working very well (Raspbian Jessie) but trying to install OpenCPN V5.0.0 on a Raspberry Pi4 (Raspbian Buster) keeps giving me this message, any ideas would be greatly appreciated, how does one go about troubleshooting this?.

I have been facing a similar issue with a pi 3.
Make sure you are using the right ppa for opencpn (raspbian buster)
ppa.launchpad.net/opencpn/opencpn/ubuntu/ bionic main
All information here :

Hope this helps !

I am having the same issue. I have installed Open cpn many times on my pi 4 and 3b+, both using buster with no problem. This seems to be a new issue.

I am trying to do a reinstall on my Pi but the link https://www.sailoog.com/blog/downloa...r-v1-0-0-noobs doesn't seem to be working. Does anyone have a link that works? My original download is on the boat computer which is in Greece and I am in London

[rgleason]

Try this https://archive.org/details/openplotter_v1.0.0_noobs

It seems to be working now, Boston, Ma.

Give V2 beta a try
OpenPlotter 2 roadmap

___________________
Option B: Install OpenPlotter on any computer running a Debian based system (Raspbian, Ubuntu, Mint...)

Open a terminal and install the dependencies:

Code:
sudo apt update
sudo apt install python-configparser python3-wxgtk4.0 python3-ujson whois

To install the main app openplotter-setting, download the latest deb package from: https://github.com/openplotter/openp...tings/releases

After downloading the deb file, you can install it by double click or typing this in a terminal:

Code:
sudo dpkg -i openplotter-settings_x.x.x-xxx.deb

Go to Main menu->Others->OpenPlotter settings and install the rest of apps from there.

hello Mike glad to see I am not the only person, I even went to the distro (Ubuntu Buster main) and can see opencpn, I just wish I knew where to start to trouble shoot, any ideas?

I am trying to get openplotter setup on a PI -4 in headless mode. I can get the install working and connection made in VNC. As soon as I execute raspi config or let the updates execute, I either get "currently can not show desktop" popup on VNC or absolutely no connection on VNC. Putty also will not connect.
Does anyone have a fix for this.???

This is a known problem with VNC see here Explicitly setting the screen resolution usually solves the problem.
