hello, I mistakenly added an etc/apt/sources.list line for "jessie"(backports) instead of "stretch", which is my current release. I proceded to update apt and installed Wine (along with many packages, some i386) from the jessie-backports source (i.e. apt install wine/jessie-backports). Please tell me how I can locate all wrongly installed packages and remove them, and install correct packages from stretch-backports, thank you,
