Package: libfm-data Version: 1.3.1-1.1 The xarchiver command to create archives is wrong. Rather than "--add-to", it must be "--compress".
The bug has been reported upstream (https://github.com/lxde/libfm/pull/69), but I don't know whether it will be applied before the freeze for bullseye. Debian GNU/Linux 10.0 Kernel 4.19.0-12-amd64
