ochartsng plugin in AvNav container is outdated and incompatible with o-charts shop

[SampoKos]

The avnav-ochartsng plugin bundled in the HaLOS AvNav container is outdated and no longer compatible with the current o-charts shop API. Attempting to log in to the OChartsNG page results in:

Error: Invalid version of the plugin code: 5

Existing charts continue to work, but it is not possible to download new or updated charts from the o-charts shop.

Environment

• HaLOS image: Halos-Desktop-Marine-HALPI2
• Container: marine-avnav-container
• Plugin path: /usr/lib/avnav/plugins/ochartsng/

Steps to reproduce

1. Open https://avnav.halos.local/
2. Navigate to User Apps → OchartsNG
3. Click the LOGIN button
4. Error: Invalid version of the plugin code: 5

Root cause

This is a known upstream issue: wellenvogel/ochartsng#33. The o-charts shop has updated its API and requires a newer version of the plugin. The upstream fix is already available.

Expected behavior

The AvNav container image should include an up-to-date version of avnav-ochartsng that is compatible with the current o-charts shop API.

Suggested fix

Update the avnav-ochartsng package version in the AvNav container image definition (halos-marine-containers). The latest release is available at https://github.com/wellenvogel/ochartsng/releases.

Workaround

None known at this time without modifying the container image manually.

Update after investigation

The AvNav container is using a third-party image xfreex/avnav-stable:20251028 which has not been updated since October 2025. The latest tag on Docker Hub points to the same image, so pulling latest does not help.

Temporary workaround

It is possible to update the ochartsng plugin inside the running container without replacing the image:

sudo docker exec -u root avnav bash -c "apt-get update && apt-get install -y avnav-ochartsng"

This upgraded the plugin from 20250822 to 20260304 (from free-x.de repository which is already configured inside the container). The o-charts shop login now works.

Note: this fix is not persistent — it will be lost if the container is recreated.

Request

Could HaLOS either:

1. Push xfreex to publish an updated image, or
2. Switch to a more actively maintained AvNav image that includes an up-to-date avnav-ochartsng
