I'm really sorry for posting this. I know it may have been asked a thousand times. I have googled like crazy and I'm on the verge of desperation here.

Basically, I followed this guide:

http://motionsoundfx.com/2012/05/ubuntu-vnc-afp-macosx/

To create a small personal file server. When I installed it, I was able to connect to it just fine, I connected with my Ubuntu username and password and I was able to see the home directory. But later, I had to restart the file server so I could prepare a couple of other hard drives to put in.

When the server restarted, I tried to connect to it, but I got an error message on my Mac:

"The version of the server you're trying to connect to is not supported. Please contact your system administrator to solve this problem."

Again, I have googled like crazy for this, and everybody says it is a problem with OS X Lion and up (assuming it affects Mavericks too). I have tried all the fixes mentioned for Lion and Mountain Lion and I haven't had any luck. That's the reason I'm posting this here: I suspect the problem is with my Ubuntu server. This happened after I restarted the server. Before restarting the server, I just put in my credentials and saw my home directory. Something when I restarted the server must have been messed up.

I have found some other solutions, including to use "SHX2" in the conf file, but it hasn't worked for me.

I ask for your help to solve this issue.

Also please understand I'm completely illiterate when it comes to Linux. This is a nice chance to me to learn the OS so please give me detailed steps to do things if you deem it necessary. Thank you!

I'm using Ubuntu Server 13.10 (the latest one as of today).
