[Bug 1682759] Re: usermod -G username:www-data remove primary user from sudoers group

[Etienne Papegnies]

Reading from the usermod manual, this is expected behavior:

       -G, --groups GROUP1[,GROUP2,...[,GROUPN]]]
           A list of supplementary groups which the user is also a member of.
           Each group is separated from the next by a comma, with no
           intervening whitespace. The groups are subject to the same
           restrictions as the group given with the -g option.

           If the user is currently a member of a group which is not listed,
           the user will be removed from the group. This behaviour can be
           changed via the -a option, which appends the user to the current
           supplementary group list.
