User Maverick Group failed

can you paste the output of

"cat /etc/passwd" and "cat /etc/group" so that we can see what users and groups got deleted?

to get back the ssl-cert group you can run

"sudo addgroup --gid 112 ssl-cert"

I run this last command, sudo addgroup --gid 112 ssl-cert, but here are the same error.

syntax error: unknown group 'crontab' in statoverride file

sudo addgroup --gid 102 crontab

if you need other groups to, look at my /etc/group and use the sudo addgroup-command to add them

also, why is your user in the root-group? its a bad idea to put the user there. normally you are putting a user in the admin-group and use sudo instead of a real root-account. please remoce your user from the root-group as it is a big security issue

Ok man I go to do that, thanks for you help.
