o-charts, charts not displaying

Hi. So, I've just made a fresh installation of OpenCPN (5.8.4-1) on the Pinebook Pro using Flatpak. I have a USB dongle for the encrypted admiralty charts from o-charts, and the plugin installed (2.0.0.64). The plugin's screen in the chart configuration section sees the System Name as the USB dongle, and that same USB dongle is using one of the authentication slots. In other words, everything seems lined up correctly.

I can download the charts, and there is no indication of any error. Nevertheless, I do not actually see the charts! This is obviously suboptimal.

The only strangeness I see is, when starting OpenCPN, the o-charts plugin says that my dongle is using assignment 1/0. If I refresh the chart list, it correctly says 1/2.

Unsure how to debug this further...

Re: o-charts, charts not displaying

Does the chart set show up in the chart directory list at Options|Charts?


Enable chart outlines (short cut "o") - are the charts there?
Do you see the green rectangles, the chart indicators aka "Chart Piano" on the bottom of the display? Click on one.


Do you have any other charts installed, for example raster charts, using those?
Those don't quilt with vector charts.


Another point can be chart groups. Right click and select "All charts" from Chart Group entry. The "0" (zero) short cut will do the same..

No, I do not see the outline or the piano.

Yes, I have Bob Bradfield's Antares chart set. When last I had this working, there was no problem with both sets.

However... I think I see the problem. Digging in the charts directory -- where the o-charts plugin is supposed to put them, the only files are TXT files which contain various notes that belong on the charts. No vector data. There is also an XML file with one entry for each subdirectory and a key...

The exact same procedure on an Apple computer works fine. Something seems to be wrong with the process that handles the decryption plumbing on flatpak linux/arm...

Will you post the full OpenCPN logfile from startup after doing a chart database rebuild?
Thanks
