Hmm, very weird thing going on. Here's a debconf protocol dump from when I hit <back> at the mirror/http/mirror question, to when I see the same question asked again.
30 backup GET mirror/http/countries 0 US SET mirror/country US 0 value set GO 30 backup GET mirror/country 0 US SET mirror/http/countries US 0 value set FGET mirror/country seen 0 false FSET mirror/http/ountries seen false 0 false INPUT high mirror/http/countries 0 question will be asked GO Now, despite what the protocol says, it does *not* ask this question, and cdebconf continues on with no pause. I'm leaving out the timestamps from the log, but the next line occurs the same second. 0 ok GET mirror/http/countries 0 US SET mirror/country US 0 value set GO 0 ok GET mirror/country 0 US SUBST mirror/http/mirror mirrors <long list of mirrors> 0 INPUT high mirror/http/mirror 0 question will be asked GO And here it's displaying the mirror/http/mirror. So the reason the go back fails is because cdebconf thinks it asks this other mirror/http/countries question, and behaves as if the user presses ok, but the question is not really displayed. -- see shy jo
