Removing official repository from QGIS

Question

I would like to remove the official repository from several QGIS installations.

Removing the Repository from the Settings works so far with:

from qgis.PyQt.QtCore import QSettings
settings=QSettings()

test=settings.allKeys()
for i in test:
    if u'Qgis/plugin-repos/' in i:
        if u'/url' in i:
            if settings.value(i)==u'https://plugins.qgis.org/plugins/plugins.xml':
                repo_key = i.rsplit('/', 1)[0]
                settings.setValue(i,'')
                settings.remove(repo_key);

but as soon as QGIS is started the next time the repository is added to the settings again.

How can I remove it permanently?

Answer 1

I was able to remove the official repository by removing it during startup and replacing the official repository with my repository by editing the installer_data.py of the QGIS installation.

I just replaced the line where the official repository is defined:

https://github.com/qgis/QGIS/blob/ec2ddb4295badd6953237e5e9182b7903f429e5a/python/pyplugin_installer/installer_data.py#L97

old:
officialRepo = (QCoreApplication.translate("QgsPluginInstaller", "QGIS Official Plugin Repository"), "https://plugins.qgis.org/plugins/plugins.xml")

new:
officialRepo = ("my Repository name", "my repository url")

Answer 2

Your code is correct, but the official repository can't be deleted. Every time you open QGIS it's reset (file installer_data.py, on my pc "C: \ OSGeo4W64 \ apps \ qgis-ltr \ python \ pyplugin_installer \ installer_data.py ").

To avoid this you can create a startup.py file, but I do not know if it can work.

Another solution is to make a minimal plugin, that simply execute that code, that way you could avoid it and you will only have to copy that plugin in those machines
