Mono-core causing update failures

I installed mono-core as a requirement to run Duplicati under Fedora 30 workstation. I am running Duplicati - .

Here are the errors I get when running a standard dnf update

sudo dnf update

Problem: mono-core-5.18.1-7.fc30.i686 has inferior architecture

  • package monodoc-5.18.1-7.fc30.x86_64 requires mono-core = 5.18.1-7.fc30, but none of the providers can be installed
  • cannot install both mono-core- and mono-core-5.18.1-7.fc30.x86_64
  • cannot install the best update candidate for package monodoc-5.18.1-7.fc30.x86_64

Welcome to the forum @jimkd1yv

Duplicati installation Prerequisites shows how to install mono, but more probably-current directions are at

Having said that, I don’t see a Fedora 30 download link at Mono Project, so maybe you could get mono at
or maybe

I don’t use Fedora or dnf, but you appear to have some sort of architecture mismatch between parts of mono that could perhaps be avoided by installing larger chunks with more expertly made dependencies.
