Using the latest kernel 4.19.27 Did the latest updates.



to get the Acces Point working again:


sudo systemctl enable hostapd.service

Probably the easiest is to undo what you did and follow the instructions from the manual. Which means

sudo apt-get install software-properties-common #You may already have it installed
sudo add-apt-repository ppa:opencpn/opencpn
sudo add-apt-repository ppa:bdbcat/opencpn

Pavel,
I had added them manually as adding as you suggested didn't work. Any other ideas as to what I'm doing wrong? I know others have it working

what I'm doing wrong?

You're doing wrong because the tip was wrong.
Debian's apt doesn't know ppa. You should manually add the gpg keys and then do the following repositories

deb Index of /opencpn/opencpn/ubuntu xenial main
deb Index of /bdbcat/opencpn/ubuntu xenial main

Are you really sure?

How To Add Launchpad PPAs In Debian Via `add-apt-repository` Command ~ Web Upd8: Ubuntu / Linux blog

@geoffr: You still need to change the edition name to a compatible Ubuntu release, I somewhat think that xenial should work, but in that I may be wrong.

@nohal

Are you really sure?

100%. This way works always, without installing of another packages under Debian. Launchpad proposing same way ... See attachment

[nohal]

Now I got lost, what does it have to do with "Debian apt not supporting Launchpad", which is obviously untrue (Read the link posted, and if you don't believe even that, try it yourself)?

[geoffr]

I now have it working - what I did is below.

Pavel - Raspberry pi needs it done a bit differently as the add-apt-repository isn't supported (as I found with google etc).

sudo apt-get install software-properties-common
sudo apt-get install dirmngr

Edit /etc/apt/sources.list add:

deb http://ppa.launchpad.net/opencpn/opencpn/ubuntu/ xenial main
deb http://ppa.launchpad.net/bdbcat/opencpn/ubuntu/ xenial main

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 67E4A52AC865EB40
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 284976FD7425C74D

sudo apt-get update

sudo apt-get install opencpn

Hope this helps others who stumble on this thread..

ps. now onto actually testing OCPN4.99 on a Pi!

[bdbcat]

geoffr...


Important and useful post.


This needs to find its way into the Wiki before O5 release.


Thanks

Geoffr,
As I wrote in your other post re: the plugins. Do yourself a favor and just do a clean load of OPlotter and end the frustration. We feel your pain!
You can always load new versions separately of OCPN that come out into plotter. If you didn't see our article on how we built our nav. computer w/Rpi here it is again.

Bill,

I'm not following what your point is....

I do have OpenPlotter running on one of my Rpis with 4.8.8. What I wanted to do was get 4.99 going to test it out and understand how well it works with the new charts I'm creating (from a performance standpoint) and also how well the split screen will work on our small touchscreen..

As far as I know there isn't an Openplotter version with 4.99 yet..

Geoff.

My point is you should be able to update the plotter 4.8.8 by selectively installing OCPN 4.99 (per the plotter manual).

A hopefully relevant question, especially for n00bs: is there a prepackaged distro (Linux distribution) for Raspberry Pi or other small computers that has most/all of the useful marine apps installed?


A few years back I tried Marinux and others on an ASUS eee netbook, with some success. I'm just wondering if there's currently a distro like this that can be put onto an SD card and run without hassles on an RPi 3. Thx.

Ov5 is great on my RPI 3, except with OpenGL on. It becomes very very very slow (8 seconds to hide the icon bar and I have time to drink a cup of coffee between zooms).
I tried true anf fake KMS with the same issue and Glxgears give around 50 fps.
I have to turn OpenGL off then sadly no MBTiles available.

[Bill O]

Yes we were also told running opengl will bog it down/crash it and wasn't stable.
Hoping w/the release of the new pi4 sometime this year, it will fix that issue.
