[Trisquel-users] Re : Update Manager is not Asking for Authorisation Password

[magicbanana]

As far as I understand, 'sudo' is called by 'gksu', itself called by the  
application requiring administrative privileges (and, yes, these privileges  
are definitely needed to install *any* program, i.e., to write in folders  
such as /usr that must be owned by root:root). The variable  
"timestamp_timeout" in /etc/sudoers (which must *always* be edited with  
'visudo') is used to specify the "number of minutes that can elapse before  
sudo will ask for a passwd again" (excerpt from 'man sudoers'). In my  
(non-customized) Trisquel, this variable is not set in /etc/sudoers and the  
default value, 15 minutes, holds.
