** Description changed: gnome-control-center added a Recommends: libnss-myhostname years ago so that it was possible to easily change the hostname in the Details panel. That dependency no longer appears to be needed. Testing Done ============ In both Debian Testing and Ubuntu 18.04 (Debian doesn't use systemd-resolved so seemed useful to try there too). sudo apt uninstall libnss-myhostname Restart Open the GNOME Settings app (gnome-control-center) In the left sidebar, click Devices Enter a different Device name in the block Open a terminal and verify that the hostname has been changed. Other Info ========== There are concerns about having libnss-myhostname in the default install. See comment 5 at LP: #1741277. See also LP: #1162475 Note that /etc/hosts isn't updated regardless of whether libnss-myhostname is installed (I guess my bug description there was wrong but there was some kind of bug there.)
