KPM恢復Ubuntu的：請求的功能未實現

Question

我試着在我的Ubuntu 14.04 運行asp.net家庭樣本，但在每一個KPM恢復我得到如下：

wuetrs@wuetrs-N750JK:~/repos/Home/samples/HelloMvc$ kvm list 

Active Version    Runtime Location    Alias 
------ -------    ------- --------    ----- 
    * 1.0.0-beta2   Mono ~/.kre/packages  default

爲KVM列表顯示，我有KRE-Mono.1.0.0-beta2安裝 所以我試圖改變package.json以獲得1.0.0-beta2包，但可能它沒有任何關係:(

我的單聲道版本是：

wuetrs@wuetrs-N750JK:~$ mono --version 
Mono JIT compiler version 3.2.8 (Debian 3.2.8+dfsg-4ubuntu1) 
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 

有什麼想法嗎？

，建議b @SuhasJoshi解決方案是正確的：

sudo apt-get remove mono-complete (or whatever package was installed) 

然後使用去： http://www.mono-project.com/docs/getting-started/install/linux/
