@Pysis868 can you revert the changes in mangosd.conf.dist.in

The build system populates this and it should not be set to a value

[Pysis868]

Confirming *.in file removed, and see no others there.
If problem is recreated at all, I suggest gitignore, or may be better, moving actively used file out of source tree, to the build one.
