Exception when running kpm restore on sample apps

[markejfmunro]

Hi,

I have a fresh install of Ubuntu 14, mono and kpm etc and I have downloaded the samples apps to test and when I run kpm restore I am getting the following exception.

mark@ubuntu:~/Home/samples/HelloWeb$ kpm restore

It's a bug in Mono's git HEAD atm.

I moved back to the official 3.12 release for the time being.

[markejfmunro]

What is the best way to go about moving back to 3.12, I am new to this configuration

[Tragetaschen]

That depends on how you installed Mono 3.99.0 from today. sudo make uninstall comes to mind.
As for installing 3.12, just follow the instructions on the link above.
