Hi Gaudenz, The state of the overall Mono ecosystem in somewhat orphaned by upstream since around 2019 [1]. GUI applications are especially affected by this. Also, there was a low-level issue affecting Mono's (de-)serialization, that made .qrt files produced by the Linux version of QuickRoute not entirely compatible with the Windows version or DOMA. I am afraid, the most reliable approach nowadays is to run QuickRoute (the official, Windows-based version) through wine.
Thanks, Kristóf 1: https://www.mono-project.com/ P.S.: You mentioned that your are willing to help with sponsoring uploads. Could you review https://mentors.debian.net/package/quickroute-gps/ ?
