On Debian jessie,
systemd-tmpfiles-clean.service fail because
/usr/lib/tmpfiles.d/xpra.conf references the group xpra, which does not exist:
systemd-tmpfiles: [/usr/lib/tmpfiles.d/xpra.conf:3] Unknown group 'xpra'.
I believe the package should create the group at install time.
Thanks, that does it.
However, a slightly cleaner way to check for group existence would be
if ! getent group $SERVER_GROUP >/dev/null; then
I've backported this change to v0.16.x in r11706 and will be included in 0.16.1
