It means what it says - we do not have OpenCPN 4.0.0 packages for the newest Ubuntu version.
If you use Ubuntu 15.10, you have to use OpenCPN 4.1 beta.

Pavel Hello, hello Petter 05,

BUT :
O 411108 appears to have taken the place of O40. That is, when I click the O icon, in the launch bar, is O411108 that opens.

First question: Is it possible to still operate Ø400 without losing operation O411108?
Second question: How can I uninstall a version of O?

Thank you in advance. Gilletarom.

Gille, If I understand you properly, Choose to do a parallel install so the two versions are in different subdirectories, say \Opencpnv4.00 and \Opencpnv4.1.1108

There should be a choice in the installation sequence.

No easy way to do a parallel install of opencpn on linux from the ppa. You can simply download the deb package and decompress the archive, but it os not exactly beginner friendly and you should kind of know what you are doing.
To uninstall on ubuntu/debian linux:

sudo apt-get remove opencpn

Hello Pavel, hello Petter05,

For memory :
- With your help, I was able to install OpenCPN 40, on my EeePC, Linux Ubuntu 14 (Trusty)
- Then I managed to install OpenCPN 411108.
As you have confirmed me, 0 411108 took the place of OpenCPN 4.0
- Then using the command indicated by Pavel I uninstalled OpenCPN.
- Then I wanted to reinstall OpenCPN 4.0.
You can check with the attached file, which is a copy of the terminal window, that I have used the "ppa" opencpn for this re-installation.

BUT :

When I launched OpenCPN, the screen announced OpenCPN 411108

Strange.

I started twice un-install OpenCPN and re-install OpenCPN (with ppa "opencpn"). After un-installation, the "Search" tool of Linux, found no software named OpenCPN. After each re-installation is 411108 O that started.

What about?

Thank by advance. (Remove .doc extend)

Not strange at all. By default, always the newest version of the package available across all your configured PPAs is installed.
Your options to get back to 4.0 are:

• Remove the beta PPA from your system and do

  sudo apt-get update && sudo apt-get remove opencpn && sudo apt-get install opencpn

• Use version pinning (Described in detail at https://help.ubuntu.com/community/PinningHowto and in the documentation linked there). Probably a bit complicated at first...

Strict version consistency you get on Linux comes at a price - it is not that easy to make it a mess

Hello Pavel,

Indeed, at first reading, this page is incomprehensible: https: //help.ubuntu.com/community/PinningHowto

It will take several nights of sleep to understand .... can be.

Thank you anyway. Gilletarom.

A very simple way to run different versions will be to run from a USB stick with Xinutop. Just make two different USB stick's with your prefered verrsions and boot from the USB. Since Xinutop loads into ram, it will run faster than form a SSD even when booted frrom a usb and running Opencpn. Very simple and failproof solution to your problems.

It's too complicated.

First :
Remember that our USB ports are not enough of them on PC. It must also be able to plug the GPS, AIS, anemometer, sounder, etc ....
Second :
I am ubuntu Linux on a 32-bit machine. This is one in which OpenCPN works. I have come to explain, in French, the simplest approach for:
- Install O4
- Install a beta
- Uninstall the beta and O4.
- Re-install O4 or the future version 4.2, when it will be ready.

And this so that the PC is as "clean" as possible.

And I have to write these explanations in French website shoreline.fr. These explanations should be easy to implement by users "alpha".

Best regards. Gilletarom.

Gilletarom...
If you are aiming at a noob's guide, forget about pinning and stay with "The version that gets installed depends on which PPA is configured in your system, once both are configured, you get the latest beta" The chance you or anybody else will come with a comprehensible tutorial about pinning is very close to none.
