Não é possível instalar nada da linha de comando

Question

sempre que tento instalar qualquer programa a partir da linha de comando, recebo a mesma mensagem

$ sudo apt-get install pycharm 
Reading package lists... Done
Building dependency tree

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
**libsnmp30 : Depends: libperl5.22 (>= 5.22.1) but it is not going to be installed
 pycharm : Depends: java-openjdk7-jre but it is not installable or
                    java7-runtime
           Depends: pycharm-data (= 2017.2.3-1~getdeb1) but it is not going to be installed**
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
