Bug#645723: general: asks for root password instead of user password

[Jimmy Li <jimmyli1528@gmail.com>]

Package: general
Severity: important

Apparently, anything that needs root asks for the root password instead of my
user password. Apparently, it's using su instead of sudo. Just a moment ago, I
had to manually re-add myself to the sudo group. Now sudo works, but all
applications still ask for the root password instead of the user password.
Also, I get "You are not allowed to modify the system configuration."
