on linux 4.19, I get

error creating new backup file '/var/lib/dpkg/status-old': Invalid cross-device link

when trying to install stuff on a ubuntu docker container. this seems to be an issue with metacopy https://www.spinics.net/lists/linux-unionfs/msg06109.html

issue can be worked around by running

echo N | sudo tee /sys/module/overlay/parameters/metacopy

Worked +1

No luck. Ubuntu:16.04 as well as debian:stretch-slim. Any idea?

Step 3/13 : RUN echo N | tee /sys/module/overlay/parameters/metacopy
 ---> Running in xxxxxxxxxxxx
tee: /sys/module/overlay/parameters/metacopy: Read-only file system

The command '/bin/sh -c echo N | tee /sys/module/overlay/parameters/metacopy' returned a non-zero code: 1

Initially, I thought it was inside the docker image that needed to be placed, but its actually on the host that you need to run the command
