"anbox version" fails with error message

[Ingo-FP-Angel]

Device: FP2 Channel: 16.04/RC (2018-W48) Anbox-Version: don't know (did "anbox-tool upgrade" today)

Problem description: Running anbox version to find out the version to enter above, I get the following error:

anbox local-/bin/sh: 1: git: not found

What were you expecting?: I was expecting to get some version number output.

Additional info: I made the root fs read-write and installed git, but that doesn't help, the problem remains.
