Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** So I run debian sid and mono-complete is now replaced by another package. This lead to the plug-ins not being compilable any more at startup of keepass2. What I did to resolve was to install mono-mcs, which subsequently lead to the installation of mono-4.0-service:amd64 (6.14.1+ds-2), libmono-profiler:amd64 (6.14.1+ds-2), libmonosgen-2.0-1:amd64 (6.14.1+ds-2, automatic), mono-csharp-shell:amd64 (6.14.1+ds-2), libmono-2.0-1:amd64 (6.14.1+ds-2), libmono-cil-dev:amd64 (6.14.1+ds-2) of which I'm not too sure of which are needed to be able to compile plug-ins again, but now I can start keepass2 again and use my plug-ins. Kind regards Sebastian
