我试图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。 两个安装失败。 我使用了这个官方的安装指南。
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 Reading state information... Done 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.
有谁知道一个解决scheme？
谢谢，乔迪
尝试以下操作：
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
假设你在ARCH 64位系统上，那么你可以通过以下方式获得这个包：
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
