The installation package you downloaded needs to be made executable before it can be used further. Run the following command for this purpose:
$ chmod 755 [package name]

$ sudo ./[package name]
Example:
sudo ./xampp-linux-7.2.10-0-installer.run
Voila!
If there's any problem whatsoever, use the following command
$ sudo chmod 755 /opt/lampp/phpmyadmin/config.inc.php
And, to start the xampp server
$ sudo /opt/lampp/lampp start
For GUI
$ sudo ./opt/lampp/manager-linux-x64.run
