Problem still persists on Debian 12. Installing Grommunio from scratch on Debian 12 using the supported/official repository is still a pain in the arse. The file/folder permission issues have not been fixed either, the MGMT interface is inaccessible when following the official Grommunio Docs! No license can be uploaded, the API is throwing tons of Error 500s and much more!
Yes I know, I can easily fix this manually and it shouldn't bother me, but that's not the point. You cannot quickly deploy Grommunio on Debian 12, it's frustrating and takes a lot of time to keep track of all those quirks just to get a working system.
Once again I am offering you my voluntary help -- I would love to feed your bugtracker if it saves you time and makes your life easier.
