Public bug reported:
The default /etc/adduser.conf contains the line:
#NAME_REGEX="^[a-z][-.a-z0-9_]*\$"
Commenting this out in preparation of updating it does not work as
expected:
pra@PABELN-X1E:~$ grep NAME_REGEX /etc/adduser.conf; sudo adduser testuser
NAME_REGEX="^[a-z][-a-z0-9_]*\$"
adduser: Please enter a username matching the regular expression configured
via the NAME_REGEX[_SYSTEM] configuration variable. 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$' ...
Adding new group `testuser$' (1002) ...
Adding new user `testuser$' (1002) with group `testuser$' ...
Creating home directory `/home/testuser$' ...
Copying files from `/etc/skel' ...

Removing the backslash escaping the terminal `$` corrects the issue:
pra@PABELN-X1E:~$ grep NAME_REGEX /etc/adduser.conf; sudo adduser testuser
NAME_REGEX="^[a-z][-a-z0-9_]*$"
Adding user `testuser' ...
Adding new group `testuser' (1002) ...
Adding new user `testuser' (1002) with group `testuser' ...
Creating home directory `/home/testuser' ...
Copying files from `/etc/skel' ...

I reported this for the `adduser` package because it seemed the closest
match. The file /etc/adduser.conf is not owned by any package.
