The groups 'mail' and 'wheel' are not found on SUSE Linux Enterprise Server for SAP Applications 15.

Hello,

I have 2 questions about 'SUSE Linux Enterprise Server for SAP Applications 15 SP1'.

I made a server on AWS, and logged in it.
I added a user as following, but the error "Group 'mail' not found" occurred.


ip-10-0-20-99:~ # useradd user1

Group 'mail' not found. Creating the user mailbox file with 0600 mode.

And I tried to add the user to 'wheel' group, but 'wheel' group is not found.


ip-10-0-20-99:~ # usermod -G wheel user1

usermod: group 'wheel' does not exist

I checked the groups, but 'mail' and 'wheel' are not found.

Question1: Why are the groups 'mail' and 'wheel' not found?

Question2: In case the groups 'mail' and 'wheel' don't exist, is there any problem?

Thanks.

    Hi and welcome to the Forum :)
    The groups where split out into there own packages, I suspect there are no packages installed that will pull them in with 'requires'.

    I see;

    zypper se wheel mail
    S  | Name               | Summary                                            | Type
    ---+--------------------+----------------------------------------------------+--------
    i  | mailx              | A MIME-Capable Implementation of the mailx Command | package
    i+ | system-group-wheel | System group 'wheel'                               | package
    i+ | system-user-mail   | System user and group mail                         | package
    
    cat /etc/group | egrep "wheel|mail"

  • Hello,

    I installed "system-group-wheel"and "system-user-mail",
    then 'wheel' and 'mail' groups are added.

    Thank you so much for your prompt response.
