OpenMarine

When I run the OpenCpn installer and press "check version"   .. see this on the command line:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/openplotterOpencpnInstaller/openplotterOpencpnInstaller.py", line 193, in OnToolCheck
    self.logger.WriteText(+' OpenCPN '+str(self.table['debian']))
TypeError: bad operand type for unary +: 'str'


and on the screen just:

Debian/Ubuntu. Recommended for: LTS systems, headless systems.

Installed: none
Candidates:
Debian/Ubuntu:

And there it stops.   Installer is  3.3.0-stable


I normally run the flatpack OpenCpn ... but ti seems to have decidd not to allow accelerate dgraphics today .. sigh.

Any clues? I just need to get the latest flatpak reinstalled, hopefully then the opengl works again ...

OK I can see the error in code. No one reported this before because the condition to run that code never happened (opencpn version in Debian official repository being the candidate) but I do not understand why the Debian version is the candidate in your system.

I will fix this ASAP but please send me the output of this command in a terminal:

apt-cache policy opencpn
