Bug#797563: installation-reports: Non-free install with disabled root user, sudo command not found

Date: 2015-09-07

Comments/Problems:

"sudo" is mentioned several times in "/var/log/installer/syslog":

Sep 7 02:04:20 user-setup: Adding user `debian' to group `sudo' ...
Sep 7 02:04:20 user-setup: Adding user debian to group sudo
Sep 6 21:04:20 gpasswd[5429]: user debian added by root to group sudo
...

I also tried the new 8.2.0 non-free ISO (http://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/8.2.0-live+nonfree/amd64/iso-hybrid/debian-live-8.2.0-amd64-standard+nonfree.iso), but I received the same result:

Sep 10 13:59:33 user-setup: Adding user debian to group sudo
Sep 10 08:59:33 gpasswd[5403]: user debian added by root to group sudo
