Specify user/uid group/gid does not work for Ubuntu

[lhondareyte]

Hi,
I try to build a package (that works for redhat/centos), but I have a problem of ownership. For example, the following file list

f 644 user group /usr/local/foor/bar

On RedHat, this works even if the user/group does not exist on the build system. On Ubuntu (22.04), the user/group must exist on the build system otherwise the file will belong to "root" after installation. I don't know the details of Debian packages but is it possible to have the same behavior as on RedHat.
Regards,
Luc
