That dependency no longer appears to be needed since we switched to systemd-resolved. - Testing Done - ============ - In both Debian Testing and Ubuntu 18.04 (Debian doesn't use systemd-resolved so seemed useful to try there too). + Test Case + ========= 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 + Enter a different Device name in the block (let's say new-hostname) Open a terminal and verify that the hostname has been changed. - - In Debian, running `ping new-hostname` fails, but it works fine in - Ubuntu. + Then run ping new-hostname and verify that that command works in the terminal. 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.) Regression Potential ==================== To quote from the manpage: https://manpages.debian.org/unstable/nss-resolve "Note that systemd-resolved will synthesize DNS resource records in a few cases, for example for "localhost" and the current hostname, see systemd-resolved(8) for the full list. This duplicates the functionality of nss-myhostname(8), but it is still recommended (see examples below) to keep nss-myhostname configured in /etc/nsswitch.conf, to keep those names resolveable if systemd-resolved is not running." Ubuntu uses systemd-resolved by default and it's expected that users who don't want to use that will need to configure some things manually.
