Hello everyone,

I am a beginner working with Xampp, I manage to install it easily but MySql is not starting. I went to check the logs and this is whats displaying all the time:

I have tried to google as much as possible but there are not many substantials advice on the matter. I will appreciate any help.

Thanks!

Open a terminal, change to /opt/lampp/var/mysql and run a "ls -la". Show us the output.
