Homeseer Windows->RPi3 Migration

I've seen this issue in a few threads on here but I never saw the resolution. When migrating from Windows to Linux Homeseer, I see this error on startup after restoring the backup. The version is on both Windows and Linux:

None of the events can be restored. Other than that it seems to run properly and can save new events. Anyone know the resolution? Thanks!

You might try updating your mono installation to V4.x

Ah yes, thanks, that did eventually solve it. It's a little tricky to get mono 4.XX on Raspbian, since the Debian repos provide 3.2.8. The following link has instructions to add the mono repos directly:


Luckily they do work on RPi3, but it's a chore to get all of the packages to upgrade (some of the 3.2.8 class libraries seem to have stuck around an interfered in a different way).

Here's what you want to see:
pi@raspberrypi:~ $ mono --version
Mono JIT compiler version 4.8.1 (Stable Wed Apr 12 12:47:01 UTC 2017)

Thank you for this response, I am migrating from Windows to Ubuntu 14.04, and this also helped solve my problem! I was very close to giving up and going back to Windows 32 bit.

Oddly enough, I installed mono 5 without knowing that was a thing... I wonder if that's why some of my devices are not acting right. Anyway, it's a lot better than 3!
