Pasting the inner error for easier browsing:

Could not load file or assembly 'System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

@erkinalp, this looks like a problem with your Mono install. I just tried this in Ubuntu and there was no error.

[HebaruSan]

A web search for this error turns up some references to people attempting to make .NET Core code talk to .NET Framework. If that's happening here, it's probably not going to work; install Mono:

[erkinalp]

This is with what CKAN automatically pulled as its dependencies. Works perfectly if I manually install mono-complete.

[HebaruSan]

Ahh, so maybe the .deb dependencies need to be updated (mono-complete is unfortunately not allowed here):

CKAN/debian/control.in

Line 6 in e78cf0e

Depends: mono-runtime (>=5.0), ca-certificates-mono, libmono-microsoft-csharp4.0-cil, liblog4net1.2-cil, libnewtonsoft-json5.0-cil, libmono-system-net-http-webrequest4.0-cil

Can you report whether installing libmono-system-servicemodel4.0a-cil fixes it?

[HebaruSan]

OK, on my Ubuntu, I removed mono-complete and as many other Mono packages as apt would let me with ckan installed, and I still have libmono-system-servicemodel-internals0.0-cil installed (and consoleui is still working). If I try removing that, apt attempts to remove ckan, suggesting an indirect dependency is already in place:

$ sudo apt remove libmono-system-servicemodel-internals0.0-cil

Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
  ckan libmono-system-runtime-serialization4.0-cil libmono-system-servicemodel-internals0.0-cil libnewtonsoft-json5.0-cil

[HebaruSan]

Update, pressing ctrl-R to refresh the mod list now throws the same System.TypeLoadException, so I can experiment with installing more dependencies...

... confirmed, sudo apt install libmono-system-servicemodel4.0a-cil fixed it.

@erkinalp, thanks for the report and for reviewing the fix pull request!
