Got everything updated except apache2. Seems it has dependency issues. tells me to use apt-get install -f. that tries then returns

"errors were encountered while processing:
/var/cache/apt/archives/apache2_2.4.10+deb8u1_armhf.deb
E:Sub-process /usr/bin/dpkg returned an error code (1)"

Tried to purge apache2 but get dependency errors doing that too.

Ideas?
