The previous comment was a red herring. It turns out it doesn't matter if uuidd is self compiled or not. The system uuidd also works perfectly if it is started in the terminal simply by
sudo uuidd However systemd starts uuidd with /usr/sbin/uuidd --socket-activation which probably makes a difference. ** Bug watch added: github.com/util-linux/util-linux/issues #1704 https://github.com/util-linux/util-linux/issues/1704 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1976630 Title: uuidd appears to be broken on Ubuntu 20.04 LTS Status in util-linux package in Ubuntu: New Bug description: uuidgen -t returns a correct result when uuidd is _not_ running. See the following transcript vdbergh@pl:~/$ sudo systemctl stop uuidd.service uuidd.socket vdbergh@pl:~/$ uuidgen -t ef485202-e275-11ec-b7ab-448500dea459 <---- (correct: last part is the MAC address) vdbergh@pl:~/$ sudo systemctl start uuidd.service vdbergh@pl:~/$ uuidgen -t f8e7b3ca-e275-11ec-b074-1d42fae212d0 <---- (incorrect) The same issue appears with every program that relies on libuuid. Example: uuid.getnode() in python3 is supposed to return the MAC address but this only works if uuidd is not running.
