After many problems with postfix not starting because the port 25 was, mysteriously, in use by nothing, I decided to do a fresh install. The OS and the webmin was installed automatically by my hosting provider.
After the installation, I tried to install the default package of virtualmin. This is what I get every time(I made more than 5 fresh installs with the same results):

If you have any idea of what is happening it would be amazing.
