BUG DESCRIPTION EDIT:
This Bug has nothing to do with a permission problem in Ubuntu (I tried to edit
my description but it was not possible)
STEPS TO REPRODUCE THE BUG:
1- Build a docker image as follow:
FROM ubuntu:latest
RUN apt-get clean && apt-get update \
&& DEBIAN_FRONTEND=noninteractive apt-get install -y \
tshark
2- Run docker container on the image with a mount -bind of the local folder
where the pcap file are stored.
Example:
docker run --name debugtsharkcoredumped -it --mount
source=/.../my_pcap_captures,target=/.../my_pcap_captures,type=bind imageTAG
3- Run in the container the tshark command tshark -r "mypcap.pcap"
--export-objects dicom,dicomdirectory
