after disinstalling/reinstalling APache2 on my Pi (with raspbian jessie), i had an issue with apache2-bin & apache2-data,
which are presumed to have non satisfied dependencies. The warning message recommended to upgrade to version 2.4.25-3 instead of current 2.4.10-10+deb8u7 for both, which i made. But it didn't change anything.
I also have no more apache server and no access to my nextcloud...
