Comment (by ryandesign):

 Replying to [ticket:59836 manulcaux]:
 > this should be made clear that sudo is mandatory, first in the output
 message given after the selupdate,

 Although we do not recommend it (because it is less secure), it is
 possible to configure MacPorts as a non-root installation. In that case,
 sudo is not used. So what you are asking for here is for us to identify
 all the places where we advise the user to use sudo (or don't advise the
 user to use sudo and should, as you encountered here), but conditionalize
 that based on whether the user has a root installation or a non-root
 installation. That's probably several places within MacPorts base, and
 countless places within individual ports.

 > and second in the error message sent if the user forgot to use sudo !

 I agree, it should print something useful. I don't know why it does not.

 > And why the sudo is not taken by default when I used it a few second
 before launching sudo port self update ??

 Because that is not how a shell works. MacPorts has no influence over the
 shell that you run it in.
