Hi there, I'm an Arch Linux user. Few days ago after the recent update of nfs-utils/nfsidmap to version 2.8.2 there was an issue. In short, if the 'static' translation method is enabled in /etc/idmapd.conf, then nfsidmap won't work at all. You can find all details in bug report I submitted to Arch repo here: https://gitlab.archlinux.org/archlinux/packaging/packages/nfs-utils/-/issues/2 They suggested it's an upstream bug and asked if I could submit it to upstream developers. So I'm doing it according to your official Wiki: https://linux-nfs.org/wiki/index.php/Reporting_bugs The best regards,
