I have picked up an old laptop. installed linux mint 19.
Now I would like to set up a local server.
I get the http working but would like https (with certbot)
Unfortunately my contents of ```/etc/apt/sources.list
i.e. deb http://ftp.debian.org/debian stretch-backports main.
is incorrect. anybody know what it should actually contain ??
then I can continue with the setup as described in …
Thanks in advance !!
