This seems like it's related to the rustup tool rather than RLS. @kinnison do you have any idea what may cause this in Docker environment?

Sorry for the delay, work has been frantic for the past month or so. This kind of problem is because Docker often doesn't cope well with removing things from one layer in a new layer atop it.

In general we recommend you do not try to change the toolchain if you have a docker with a toolchain embedded in it because Docker simply cannot cope. You should either ensure your baseline container has no toolchain in it and so rustup can cleanly install the toolchain you want; or else it should contain exactly the toolchain you want as docker can't cope with updating it.

Sadly this is not something we can easily fix in rustup because of the way Docker works.
