Debian packages are not created with root privileges

[muhdiboy]

Description
The debian packages aren't built with root:root privileges. So by installing them with dpkg (or equivalent) the files are extracted and the UID and GID are set to 1001:123, which can be literally anything on the system.

To Reproduce

• download any .deb installer package
• install (e.g. dpkg -i syncplay_1.6.9.deb)
• check file permissions with ls -l /usr/lib/syncplay or ls -l /usr/lib/syncplay-server

Expected behavior
Root ownership of the extracted files

Version and platform:

• OS: Pop!_OS 21.10
• Syncplay version and build type: 1.6.9

Additional context
The files seem to be created with runner:docker privileges.

Solution recommendation
The .deb packages could be built with fakeroot, where it is possible to easily set UID and GID to 0:0, which is always the systems root, and build the .deb package.
I've extracted and rebuilt the package with correct permissions and installed it successfully on my system. It's working without issues.

Just adding another way to check privileges of installer package:
dpkg-deb --contents syncplay_1.7.0_Beta1.deb
