Sendmail configuration issues after upgrading Debian
I've updated my instance from Debian 8 to the latest Stable release. Now, whenever I use apt, I get the following:
$ sudo apt upgrade
Reading package lists... Done

Is it just a matter of installing the missing packages? Or is there more to it? The 4 not fully installed or removed is a bit odd to me, but I'm admittedly pretty new to running a server.

I found a forum post that offers some suggestions that might help to resolve this issue for you.
Essentially, you'll just want to kill the Sendmail service then force the updates through. The following commands should take you through that process.
sudo su -
service sendmail stop
apt install -f
I hope this helps!
Thanks.
Unfortunately, that didn't work
EDIT: actually, it may have worked… had to reboot my instance for another reason, forgetting that sendmail would start on boot. Turning off the service first, like in your solution, then forcing the installation seems to have done the trick. I no longer get dpkg errors when running apt anything.
Thanks!
