Hi, Those are two independent cases.
1.) The MRs for src:libfm and src:libfm-qt are for xarchiver command. Long time ago xarchiver upstream changed from --add-to to --compress The best place to change would be upstream lxde and lxqt. At least for lxde there is an old bug: https://github.com/lxde/libfm/issues/35 It probably just got forgotten. It's broken on buster, we should patch it for bullseye. Thanks for the "3.0 (quilt)" hint. I'll try to change the MRs at the end of the week. 2.) The MR for src:lxqt-metapackages is optional, we don't have to touch it. Only if we want lxqt-archiver to be installed as default. Therefore it adds lxqt-archiver in first place so it will be installed instead of xarchiver when users install lxqt (31) and lxqt-core (31) packages. (Now we have lxqt (30) and lxqt-core (30) packages which installs xarchiver.) We should wait until lxqt-archiver enters debian repositories, it is still in NEW. Cheers, Amy
