Thanks for reporting this bug. Reporting it against adduser was correct, since adduser creates and manages /etc/adduser.conf

Use the `--force-badname' option to relax this check or reconfigure NAME_REGEX. pra@PABELN-X1E:~$ This is due to the overeager escaping of the dollar sign, which has the undesired effect of requring that usernames end in `$`: pra@PABELN-X1E:~$ sudo adduser testuser$ Adding user `testuser$' ...
