I'm trying to install MX, but I keep getting an error.
Code: Select all
john@john-Dell-DXP051:~$ cd /home/john/CumulusMX
john@john-Dell-DXP051:~/CumulusMX$ sudo mono CumulusMX.exe
[sudo] password for john:
Current culture: English (United States)
System.TypeInitializationException: An exception was thrown by the type initializer for CumulusMX.Cumulus ---> System.TypeLoadException: Could not load type 'System.Net.Http.HttpClientHandler' from assembly 'System.Net.Http, Version=1.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

**** An error has occurred - please zip up the MXdiags folder and post it in the forum ****

I'm running Zorin OS 9 64 bit. I don't see any reason to attach the MXDiags folder, since it is empty. Let me know if there is any other information I need to post to help diagnose this error.

It can't find the file System.Net.Http.dll, or at least the version that it's expecting. The assembly is provided as part of the distribution, so I don't know why it isn't finding it. Perhaps it is loading another version because it's before it on the search path, but I believe it should first look in the current directory. I've just tried a fresh install of 3025 on my Pi, and it runs without that error. What version of mono is installed on your system (do 'mono --version')?

As an experiment, I deleted the System.net.Http.dll file from my Pi install - and it still runs without error. Perhaps the version I am bundling is not actually the required version, but there hasn't been a problem so far because everyone has that assembly installed as part of mono (it's a system assembly, as indicated by the name). Did you install Mono just for MX, or did you already have it installed? What package(s) did you install? What output do you get from 'gacutil -l System.Net.Http'?

This is what I get for Mono version:
Code: Select all
Mono JIT compiler version 3.2.8 (Debian 3.2.8+dfsg-4ubuntu1.1)
Copyright (C) 2002-2014 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com
TLS: __thread
SIGSEGV: altstack
Notifications: epoll
Architecture: amd64
Disabled: none
Misc: softdebug
LLVM: supported, not enabled.
GC: sgen
As far as I know, Mono was already installed. When I looked for it in the software center, it was shown as installed, and I don't remember installing it previously. For gacutil -l System.Net.Http I get
Code: Select all
john@john-Dell-DXP051:~$ gacutil -l System.Net.Http
The following assemblies are installed into the GAC:
Number of items = 0
Let me know if you need anything else.

This is the problem, you apparently do not have the required Mono system assemblies on your system. You need to install the 'mono-complete' package, assuming one exists for the Linux distribution you are using. This should install the required assemblies.

I think I found what I needed in the software center. I'll install it and get back to you with an update.

I found the mono-complete package in the software center, installed it, and now Cumulus seems to be running fine. Thanks for the help.
