This is trying to use autopano-sift, whereas you have 
autopano-sift-C installed.  For your version of autopano-sift-C, you 
need to change your preferences:
(from: /usr/share/doc/autopano-sift-C-2.4.1/README.fedora)
# To use with hugin, set the 'Autopano-SIFT:' preference to:
#
#   autopano-c-complete.sh
#
# ..and the 'Arguments:' preference to:
#
#   --output %o --points %p %i
Alternatively, go to the hugin 'autopano' preferences and 'load 
defaults', you'll get the default 'autopano' setting for fedora 
users.

Yes, there are now several different tools for generating control 
points and each has advantages and disadvantages.  So we are still 
not at a point where hugin can offer a single default solution that 
is good for all users.
(BTW my daughter calls me 'slilly daddy', not sure that this is a 
good thing)
