I have problems installing nethserver 7.3. My installation fails at checking installation media (at least i think so). I used more dvd’s, burnt in different computers and i get the same error every each time. I thought it’s a problem with my optical disk drive, with my dvd’s, but installing centos 7 (downloaded from centos website) gave no error. in a virtual machine everything went smooth and fine but on my real server the same error every time. I had installed nethserver 7.2 before on the same server and the installation for 7.2 went just fine.
so anyone had problems like this?
