How to install in a non-debian system

[lpvm]

This plugin is always a pain to have it running correctly.

The 1.2.1 tarball doesn't have the install scripts. What I did, from the deb package, was to install it to /opt, make symlinks from /usr/local/bin to that /opt/net.downloadhelper.coapp/bin/net.downloadhelper.coapp-linux-64 file and copied the the json file to /usr/lib/mozilla/native-messaging-hosts/net.downloadhelper.coapp.json But this has a code inside it that I don't know how to generate. Restarted firefox, but it still says can't find the companion app.

What to do?

The coapp install page describes extra steps to be executed once you have downloaded the .tar.gz package:

targz user-wide install

# tar xf net.downloadhelper.coapp-1.2.3-1_amd64.tar.gz -C ~
# ~/net.downloadhelper.coapp-1.2.3/bin/net.downloadhelper.coapp-linux-64 install --user

targz system-wide install

# sudo tar xf net.downloadhelper.coapp-1.2.3-1_amd64.tar.gz -C /usr/local
# sudo /usr/local/net.downloadhelper.coapp-1.2.3/bin/net.downloadhelper.coapp-linux-64 install --system

If you think this could be better explained, please let me know.

Hi @mi-g ,

First, let me thank you for the plugin that has served to get me some videos in the past!

Doing as mentioned, even after restarting Firefox, doesn't seem to work:

Companion application required
This operation requires an external application to be completed.

In the past, see https://github.com/mi-g/vdhcoapp/issues/17 it was solved by modifying the path in the setup scripts that are not present anymore. Don't know what to do this time. Creating a symlink ln -s /usr/local/net.downloadhelper.coapp-1.2.3/bin/net.downloadhelper.coapp-linux-64 /usr/local/bin/ doesn't result.

I have seen the following issue a couple of times, maybe you are in this case:

A user installs the coapp as a user: the coapp code goes to ~/net.downloadhelper.coapp and the manifest file has been added to ~/.mozilla/firefox/native-messaging-hosts. Then the user changes his mind, delete the ~/net.downloadhelper.coapp directory and reinstall the coapp as system, which creates /opt/net.downloadhelper.coapp/ or /usr/local/net.downloadhelper.coapp/ with manifest in /usr/lib/mozilla/native-messaging-hosts.

As a result, when Firefox tries to launch the coapp, it first looks at a user-level manifest at ~/.mozilla/firefox/native-messaging-hosts and tries to execute the pointed binary that no longer exists. You get the error you described.

The workaround consists of removing the file ~/.mozilla/firefox/native-messaging-hosts/net.downloadhelper.coapp.json that is no longer valid.

Can you check that ?

You got it @mi-g , although the json file was in ~/.mozilla/native-messaging-hosts/net.downloadhelper.coapp.json. It's working fine now. Thank you very much for your support.
