(Linux): Install JSON files on the right place for Chrome (and add Chromium support)

[klondi]

Currently, the native-messaging json file for chrome is installed on /usr/share/web-eid as a result after installing the extension it will not work as it cannot run.

Instead as stated on https://developer.chrome.com/docs/extensions/develop/concepts/native-messaging the JSON file should be installed on /etc/opt/chrome/native-messaging-hosts

With this adding Chromium support is fairly easy too. According to https://developer.chrome.com/docs/extensions/how-to/distribute/install-extensions ncibgoaomkmdpilpocfeponihegamlic.json should be installed on /usr/share/chromium/extensions/ and to allow native messaging https://developer.chrome.com/docs/extensions/develop/concepts/native-messaging requires installing eu.webeid.json into /etc/chromium/native-messaging-hosts/

In summary to address these issues:
Install eu.webeid.json into both /etc/opt/chrome/native-messaging-hosts and /etc/chromium/native-messaging-hosts/
Install ncibgoaomkmdpilpocfeponihegamlic.json also into /usr/share/chromium/extensions/

Sorry for the delayed response! We will discuss this internally and get back to you.

Spent lot of time trying to understand why web-eid is not executed from Chromium.
As a result I see the message that it's not possible to use outdated ID card software.
Thanks for solution @klondi !

We discussed this with the project leads. We are basically interested in adding Chromium support, but it is not a priority currently. We'll get back to it as other priorities allow later.
