I have a problem when I install debian distro on Duplicati. I'm trying : sudo apt-get install mono-complete cd /usr/lib mkdir Duplicati cd Duplicati wget http://updates.duplicati.com/preview/latest.zip unzip latest.zip mono Duplicati.GUI.TrayIcon.exe

I have the following error message:

'Missing method System.Threading.Tasks.Task :: WhenAll (Task []) in /usr/lib/mono/4.0/mscorlib.dll assembly, referenced in assembly /usr/lib/duplicati/Duplicati.Library.UsageReporter.dll Crash!' and more...

do you have an idea about the problem? thank you

I have tested on Ubuntu, and I have not seen that issue before.

What version of Mono do you have installed? Try: mono --version

The error is that the System.Threading.Task library is missing a required method, which indicates that you are using some strange version of the Mono libraries.

Good ! many thanks Kenneth ! i tested with : 'echo "deb http://download.mono-project.com/repo/debian wheezy-libtiff-compat main" | sudo tee -a /etc/apt/sources.list.d/mono-xamarin.list' from mono-project.com and it works !!
