I've a problem with the installation of Frrouting. when I tape this command: sudo adduser --system --ingroup frr --groups frrvty --home /var/run/frr/ \ --gecos "FRR suite" --shell /sbin/nologin frr
the result is unknow: option groups
when I change groups to group I've this message specify only one name in this mode.
so I don't know what i must to do. help me please.
the rest work normally: git clone, ./bootstrap.sh and ./configure.
when I want to start the deamon zebra with this command zebra -d i receive this message: privs_init: user(frr) is not part of vty group specified(frrvty)
