Missing virtual packages?

[senorsmartypants]

I'm trying to install several packages and it seems like they think I'm missing a virtual package.

For example
mythweb from https://www.deb-multimedia.org/dists/st ... ge/mythweb

It wants to install apache2, even thou I have lighttpd installed.

How can I determine if my system believes a virtual package is installed correctly?

A few more details about my setup.

I just recently upgrade from Jessie to stretch. Everything seemed fine with the upgrade.

I have php5.6 installed and not php7.0. Not sure how related that is to this issue, but I just noticed that.

Using deb-multimedia is a good way to mess up your system, there often are many dependency issues, also if you were using it before you upgraded, when
you upgraded, none of the packages that were installed before from there would upgrade correctly.

--- a virtual package.

What virtual package ? QEMU, Virtual Box, KVM , etc... ?
Is pretty vague, but if you know the name of the virtual package, you can check to see if it is installed.

Code: Select all

 apt-cache policy package   ->  apt list -a package

Where it says "package", should be the name of the package.

A virtual package is one that apt does not see in the repositories, not one having to do with virtualization.

It would no doubt be better if you provided the actual text of the error message that you're getting.
