[Trisquel-users] Re : Software Updater proceeds without authentication

[lcerf]

It depends on how APT is configured. Look at "Software sources" (in the  
"System settings"). The drop-down menu associated with "When there are  
security updates" can specify that such updates are automatically downloaded  
and installed, which translates to "no need for a password" (I believe).

A password is asked whenever you fire 'sudo'.
