suggests the user must be in the verticadba group (for example:
usermod -a -G verticadba <I>userNameHere</I>). If not, the installer reports this issue with identifier [S0220]. however that only APPENDS verticadba as secondary group and still not satisfies the primary group membership condition.
The correct group modification statement would be
usermod -g verticadba dbadmin
It would be also useful to add
groupadd verticadba
