Hi All
yep, I was a mistake with x64 and I thought, that packages without "32" in names were for 64-bit OS.
But anyway, system had taken what it needed and build has completed successfully.
Yes, "sudo apt-get update" works fine.
Concerning update settings:

So again, my question was: if it is known what packages should be installed to OS for content-shell successful build - why they are not included to install-build-deps.sh?
I've faced the same issue a year before, when I tried BLINK for the first time. I just hoped that such trivial issues should have been fixed already...
