Package: docker.io Version: 1.13.0~ds1-1 Severity: normal Dear Maintainer,
I tried to purge docker.io package because I no longer needed it, and the purge failed: /var/lib/docker/nuke-graph-directory.sh: 64: /var/lib/docker/nuke-graph-directory.sh: shopt: not found dpkg: error processing package docker.io (--purge): subprocess installed post-removal script returned error exit status 127 Obviously dash has no 'shopt' -- System Information: Debian Release: 9.0 APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
