Sorry, good point - only Ubuntu users could be expected to have the
keys already installed.
But even if it were only used for that case, it would be very valuable
for upgrades etc.
In general, the PGP web of trust along with various tools allows
people (and programs) to gain trust in the keys used to sign the file.
But that topic is best discussed elsewhere.
