Docker ivy command stalls with a mounted volume

[JWDobken]

Running the almond docker container with a volume mount to an empty local notebooks folder:

docker run -it --rm -v ${PWD}/notebooks:/home/jovyan/notebooks -p 8888:8888 almondsh/almond:0.13.11

Then in the Scala notebook whenever I run:

import $ivy.`org.apache.spark::spark-sql:3.3.2`

The Ammonite interpreter takes several minutes

I have tried with either Scala version 2.12, 2.13 and 3.2. I really can't explain how this mount affects the behavior.

Also, if relevant, I get many warnings:
