Oh I see! Thank you for explaining again - I didn’t read your first post carefully enough, sorry.
Yes this is a bug that needs fixing. In fact I think it is two bugs which need fixing, firstly
rclone version shouldn’t really care about the config file, and secondly the install script shouldn’t provoke that bug.
I made a new issue about this: https://github.com/ncw/rclone/issues/2127
I’ve put in a work-around in https://github.com/ncw/rclone/commit/b6058e0106cb9f155a2e3d5a575dd74c3457bfc7 and uploaded a new install.sh.
