Mono 2.4 on Ubuntu

I'm not having much luck with running mono on a fresh installation of kubuntu 9.04-amd64, even though it runs fine, with very little set-up problems on openSUSE 11.1 (perhaps unsurprisingly), and Mandriva 2009.1 on the same, multi-boot pc.

I suspect it's all in the config and I'm really hoping you (or anyone) can point me to a clean, simple and bullet-proof mono config tutorial that is known to work on Ubuntu 9.04 and its current packages. Preferably one that includes Virtual Hosting config, but maybe I can work that out for myself if I can just get it to serve asp from the default document root (/var/www).

I did try the mono-2.4 compilation in your tutorial (twice), and it seemed to go ok up to installing and checking xsp server. After that the compilation went ahead and finished, but reporting a vast slew of 'errors' all the while [non-critical, I guess, maybe?].

As it failed to serve my localhost asp web sites (which are served by suse and mandriva, as mentioned), I nuked it and went back to more conventional installations, trying apt-get, aptitude, and synaptic (with a system restore from partimage each time).

Each time the installation more or less went through, though it always hung on the mod-mono-server2 config step, then I attempt to set up the config but always the same results: either error messages (e.g. Server Error in '/' Application
Standard output has not been redirected or process has not been started.
Description: HTTP 500. Error processing request., or I get a save file dialogue when I try to hit the server.

What am I doing wrong?

Hello Russell,
thanks for that great instruction. It worked fine on my recently installed Ubuntu 9.04. Now I want to install Monodevelop. I tried to install it by using 'apt-get install monodevelop'. Installation was successful, but when I start Monodevelop there are several errors (e.g. The following assembly referenced from /usr/lib/monodevelop/bin/MonoDevelop.Core.dll could not be loaded:  Assembly:   Mono.Addins.Setup). What can I do to get it started? It would be great if you could help me.

Greetings
Matthias
