steam wants to install already installed dependencies

[Martin Wolf]

i already purged steam with "apt purge steam" and removed the .steam folder on my user but still i get on every appstart that steam wants to install unmet dependencies. when i enter my sudo password in the shell window it shows that they are already installed.

i included a screenshot with the packages it always wants to install.
