I think I got it: I modified /etc/nginx/conf.d/grommunio.conf
to adjust the port numbers.
It seems that the file is then completely skipped in the update. I would have expected at least a /etc/nginx/conf.d/grommunio.conf.dpkg-new
being created - but this is not the case.
Would be great if the packages could be adjusted so that at least dpgk-new files are written for all that lives under /etc. For the files where changes are more likely, I would even suggest to ask the admin if the file should be kept or overwritten when the installation is running.
