Public bug reported: When using `sudo --login --user USERNAME` with Ubuntu Focal currently, it will correctly operate but it will also throw the following error before continuing with the logon process:
sudo: setrlimit(RLIMIT_CORE): Operation not permitted A full run of this was tested in a Focal LXD container after dropping to a root shell to reproduce (arstotzka is the host system, focal-test is the test container): teward@arstotzka:~$ lxc shell focal-test root@focal-test:~# sudo --login --user ubuntu sudo: setrlimit(RLIMIT_CORE): Operation not permitted To run a command as administrator (user "root"), use "sudo <command>".
