I have run on my raspberry pi 3 apache web server and meteo sw Cumulus for more than year. I just run apt-get update and after that upgrade sometimes. But now I have problem with broken dependencies.
When I run apt-get upgrade it returns this :
root@web:/home/pi# apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
apache2 : Depends: apache2-data (= 2.4.10-10+deb8u11) but 2.4.10-10+deb8u10 is installed
E: Unmet dependencies. Try using -f.
How can I repair this problem ? Can you help me please ?
