Good afternoon.
About skype.
Run through the terminal with the "skype" command and see the output that will be in the console.
Did you install Skype from the official site?
It is necessary to add to the "Application Center"
Then in the console
And then install Skype.
If skype did not work, then try to do the following (terminal)
enter there
and again in the terminal
sudo ldconfig -v
