Great. So I'll now apply the patch below, which is identical to the
previous patch, except that it also modifies debian/changelog to
close the bug and bump the Debian version.

OK?

commit 72d76ae62a67fadef1612c5a868b13d2dad6f75f
Author: Andre Noll <m...@tuebingen.mpg.de>

    debian: Enable `Rules-Requires-Root: no`.
    
    During a test rebuild for building packages with `Rules-Requires-Root:
    no` as the default in `dpkg`, liblopsub failed to rebuild.
    
    The problem is the rule of the `binary` target in `debian/rules` which
    runs `install(1)` with -o root -g root to set the owner and group ID of
    the files and directories being installed. With `Rules-Requires-Root:
    no`, this fails due to insufficient permissions. This commit removes
    the problematic options in favor of running `dh_fixperms(1)` just
    before `dh_makeshlibs(1)`.
    
    With these changes in place, the build no longer requires any form of
    root during the `binary` target. Consequently, we may enable rootless
    builds in `debian/control`.
