How can I check if I still have some old packages from Jessie? I order to upgrade my Jessie to Stretch I followed the steps from this guide: https://www.howtoforge.com/tutorial/how-to-upgrade-debian-8-jessie-to-9-stretch/ And there was no steps to check and remove old packages. Can you please tell me how to do this? Regards, Piotr
