Control: reassign -1 passwd Hello,
I'm sorry for the delay. As far as Debian Unstable goes, I cannot reproduce the issue on a clean VM, so it may be limited to Stretch as you said. In any case, this part: > root@debian:~# deluser foo > Removing user `foo' ... > Warning: group `foo' has no more members. > userdel: user foo is currently used by process 4892 > /usr/sbin/deluser: `/usr/sbin/userdel foo' returned error code 8. Exiting. shows that the error is coming from userdel. deluser issued the command `/usr/bin/userdel foo` and userdel gave you this message. I'm therefore reassigning this ticket to the passwd package, which is where userdel comes from. You should hear from its maintainers as a result. regards Afif -- Afif Elghraoui | عفيف الغراوي http://afif.ghraoui.name
