thanks for answering
I created new qube with params:
-Type: Standalone qube copied from a template
-Template: whonix-ws-15
-networking: sys-whonix
and managed to install I2P, configured it, and it is running after restart. However I encounter a new error while trying to go to proxy http://127.0.0.1:7657 “The proxy server is refusing connections”
or when trying to load a web page “We’re having trouble finding that site”
