Very interesting project Volumio. Installed on Raspberry pi3. There are mistakes. Where should they report?
Hi & welcome to Volumio 
. Whereabouts in Western Siberia are you?
You can post bug reports in the appropriate forum here, or probably better for keeping track of the bugs, on the Github site.
I live in Tomsk city 
I spent a couple of weeks in Novosibirsk a long time a go at the Akademgorodok. Beautiful scenary & beautiful people. All the best to you 
It’s not far. I have been there many times!
What time of year were you here?
Summer, but I would have liked to have tried winter too… those 40cm double glazing panels must say something
