[Qgis-user] QGIS 3.4.12 python error on open plugins list manager

[Walter Lorenzetti]

I try to clear QGIS3.ini file form custom settings and clear python 
profile folder, but Now I otain this:

Si è verificato un errore durante l'esecuzione delle istruzioni 
seguenti: pyplugin_installer.instance().showPluginManagerWhenReady()

Traceback (most recent call last):   File "", line 1, in   File 
"/usr/share/qgis/python/pyplugin_installer/installer.py", line 252, in 
showPluginManagerWhenReady     
self.fetchAvailablePlugins(reloadMode=False)   File 
"/usr/share/qgis/python/pyplugin_installer/installer.py", line 120, in 
fetchAvailablePlugins     repositories.requestFetching(key)   File 
"/usr/share/qgis/python/pyplugin_installer/installer_data.py", line 325, 
in requestFetching     
self.mRepositories[key]["QRequest"].setAttribute(QNetworkRequest.FollowRedirectsAttribute, 
True) AttributeError: type object 'QNetworkRequest' has no attribute 
'FollowRedirectsAttribute'

Versione Python: 3.5.2 (default, Jul 10 2019, 11:58:48) [GCC 5.4.0 20160609]

I tried to create a new profile but same error.

I'll try to reinstall qgis
