如何在 Ubuntu 上安装最新版本的 Mono 和 MonoDevelop？

Question

我正在尝试在我的系统上安装最新版本的 Mono 框架和 MonoDevelop。昨天我尝试在 Ubuntu（14.04 LTS）和 Debian（V8.2）上安装。两个安装都失败了。我使用了这个官方安装指南。

http://www.mono-project.com/docs/getting-started/install/linux/#debian-ubuntu-and-derivatives

我执行了这个命令。

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list
sudo apt-get update

发生以下错误。

root@debian:/home/administrator# apt-get install mono-complete
Reading package lists... Done
Building dependency tree

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 mono-complete : Depends: mono-devel (= 4.2.1.102-0xamarin1) but it is not going to be installed
                 Depends: mono-4.0-service (= 4.2.1.102-0xamarin1) but it is not going to be installed
                 Depends: libmono-cil-dev (= 4.2.1.102-0xamarin1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

有人知道解决办法吗？

非常感谢， 乔迪

尝试以下方法：

sudo apt-get install libjpeg62-turbo

如果你得到：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libjpeg62-turbo is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source E: 
Package 'libjpeg62-turbo' has no installation candidate

假设您使用的是 ARCH 64 位系统，那么您可以通过以下方式获取此软件包：

wget http://ftp.br.debian.org/debian/pool/main/libj/libjpeg-turbo/libjpeg62-turbo_1.4.1-2_amd64.deb

安装 deb：

sudo dpkg --install --recursive --auto-deconfigure libjpeg62-turbo_1.4.1-2_amd64.deb 

现在安装 mono/monodevelop：

sudo apt-get install mono-devel
sudo apt-get install monodevelop
