I was rebuilding my dropbox Docker container, and it failed in 4.19 with the following error: dpkg: error processing archive /var/cache/apt/archives/perl-base_5.20.2-3+deb8u11_amd64.deb (--unpack): unable to make backup link of `./usr/bin/perl5.20.2' before installing new version: Invalid cross-device link dpkg-deb: error: subprocess paste was killed by signal (Broken pipe) dpkg: error: error creating new backup file '/var/lib/dpkg/status-old': Invalid cross-device link E: Sub-process /usr/bin/dpkg returned an error code (2) When I booted the 4.18.0-2 kernel from Debian, the exact same Docker file worked just fine. With 4.19 it fails reliably. To reproduce: git clone https://github.com/tytso/docker-dropbox cd docker-dropbox docker build --no-cache . I'm using a Debian testing (buster) userspace, using the docker-ce from dropbox.com, version 18.03.1~ce-0~debian, using overlay2 storage driverh. Does this ring a bell at all? Can someone give me some tips on how to troubleshoot this? Thanks!! - Ted
