I am not sure the cause - but there seems to be an error asscessing mariadb's repo. it's not accesible on my local pc as well.

Is it advisable to install tarball?

 

MariaDB yum repo is accessible again - but now after every successful install , it seems somehow the networking config inside the VM is broken.
