On latest debian 12 the setup does not complete successfully.
First error is:
/usr/share/grommunio-setup/common/helpers: No such file or directory
/usr/share/grommunio-setup/common/dialogs: No such file or directory
both files are located in the grommunio-setup directory. After the folder is created and the files are moved to the common folder the setup starts.
second error:
A self signed cert won't be generated and displays this error: ./grommunio-setup: line 408: selfcert: command not found
Without a cert nginx won't start.
Tested with grommunio-setup 1.1-1+3.1 from community repo.
