I did a sudo apt install libpng16-dev to upgrade filezilla. but it removed a lot of dependencies.
Now I can't install elementary-sdk and plenty of other depencies, the following error occurs.

I tried fixing broken packaged at the recovery menu but it didn't work. How can I fix this. I am running Loki
