It seems that PyCharm always updates the connected Python interpreter on startup and also scans and updates all packages if needed. For me this means whenever I open PyCharm there will be updating processes running in background and I have to wait sometimes for as good as a whole minute, which I find quite annoying.
So the question is: does there exist any way to disable this automatic update mechanism? It would be best if I can manually update Python interpreter and the packages only if I want to.
