Just tried this on CentOS 7, fully up-to-date. The first time I ran it, I got the message below:
Installing redhat-lsb! Please wait.
Done!
Error: Could not detect OS. Currently only Debian and Ubuntu are supported. Aborting!
I checked the script to get the command it used, and that returned "centos". Wasn't sure what the problem was, but I ran it again and it did not post the same error.
Also, your script gives me a username and password (Username: "admin" | Password: "NDE3ND"), but this was not the correct password; the default "foobar" password worked.
GREAT WORK on this! I really appreciate it. Can't wait to try this out.
