I've got a custom built grafana docker image that I build using
go run build.go build package
This all works fine, and I get a deb image from the process (grafana_4.3.0-1490275845pre1_amd64.deb) as well as a .tar.gz file and an rpm package as well.
When using the dockerfile (essentially copied from grafana/grafana-docker):
FROM debian:jessie
COPY ./grafana.deb /tmp/grafana.deb
RUN apt-get update && \
apt-get -y --no-install-recommends install libfontconfig curl ca-certificates && \
apt-get clean && \
dpkg -i --debug=3773 /tmp/grafana.deb && \
rm /tmp/grafana.deb && \
I get the following error:
dpkg (subprocess): unable to execute installed post-installation script (/var/lib/dpkg/info/grafana.postinst): No such file or directory
dpkg: error processing package grafana (--install):
subprocess installed post-installation script returned error exit status 2

The obvious issue is (/var/lib/dpkg/info/grafana.postinst): No such file or directory but not knowing anything about dpkg I don't really know where to start trying to debug it. As far as I'm aware, I've not altered the deployment scripts so I'm at a loss to know where the issue has arisen.
As I was developing Grafana on a shared Windows folder, with Grafana running in a Docker container on VirtualBox, it seems that (despite not editing the files) SourceTree or something else edited the source to add Windows new lines which messed up the packaging step. I just used dos2unix to remove newlines and everything started working as expected.
The particular error message was related to newlines in the postinst file, which I debugged manually with bash on the VM.
