The assembly mscorlib.dll was not found or could not be loaded

Question

I wanted to run my software on a VPS, however, when I try to run it with mono, it says

The assembly mscorlib.dll was not found or could not be loaded.It should have been installed in the '/usr/local/lib/mono/4.5/mscorlib.dll' directory.

I've already tried to install mono-complete

sudo apt-get install mono-complete

However, it says mono-complete is already the newest version.

Is there anything I can do to fix it?

Sincerely, Mike

( I run on my VPS on ubuntu 13.10 64 bit, and my mono version is 4.0.0)

Solution

I came across the problem last day.You need to install mono-2.0 to execute certain programs.

To install mono 2.0 ,open terminal and type

sudo apt-get install libmono2.0-cil

Have you tried building mono manually? mono-project.com/Compiling_Mono_From_Git

Hi, Thanks for your reply, it didn't work though, it's already the newest version

@mike version 2.0 is different than 4.0 .They can be both installed at same time.If the command doesn't work, try software center.

I probably explained the it the wrong way, when I executed the command, it says it couldn't install because it was already the latest version

try sudo apt-get install libmono-system2.0-cil

You could use a symlink instead of copying.

Yes, it's better :) I did that after. And also, I set MONO_PATH correctly.
