Installing mono-complete solved problem. Thank You very much. I wasn't aware, that dependencies of keepass2 package won't be sufficient.
I'm using version AutoTypeSearch-v1.0 When I'm starting Keepass with plugin I can see error like in attached image. I'm using KeePass 2.43 (see attached image). I used to use the plugin some time ago (before KeePass 2.42).
Hi, It looks, that plugin is not compatible with Keepass 2.43
