Hi Greg,

Thanks.  Apologies if I'm missing something, but I don't understand how this situation could have arisen other than because of password errors somewhere or other.

Surely su doesn't require sudo?

Jerry seems to me to be saying that neither sudo nor su root succeeded, yet he still saved changes (I presume) to what I imagine is /etc/sudoers - doesn't he?

The second installation resulted in success with su root

Could someone refer me to this please?

I'm not sure if a leaving the root pw blank during installation disables use of su root, but in the case of a blank root password, sudo should have worked but it didn't.  If sudo didn't work because there is no-one in the sudo group, su should be available, and for both not to work (as in the first installation) suggests a password error, doesn't it?  The fact that sudo was made to work during the first installation (having not initially) suggests that su must have succeeded at some point, doesn't it?

Kind regards,
Gareth
