Hardy Heron open for uploads

I am new to Ubuntu (or in my case, Kubuntu, since I am a KDE guy).  I have been using, and
still use, Mandrake/Mandriva on most of my machines.  *What attracted me to Ubuntu was
precisely this "seamless upgrade" concept*.

I recently upgraded Feisty to Gutsy.  The GUI update failed multiple times (but you've heard
this before).  The command line update worked perfectly afterward.  There are many people for
whom the GUI upgrade failed, I understand from the various online fora etc.  Given that this
is one of the points that attract non-techie folks to Ubuntu, and these non-techie folks are
unlikely to go to the command line, I consider this a problem.

I must also mention that I did the exact same "network upgrade" to my Mandriva box last week.
Against the advice of the #mandriva channel folks, I did a command line upgrade (manually
remove all urpmi sources and adding new ones for the 2008 version, eqvt to changing feisty to
gutsy in /etc/apt/sources.list), urpmi --auto-update (eqvt to aptitude update; aptitude
upgrade).  Started this before I left for home; it took about 7 hours, downloaded an
astonishing 2.6 GB of stuff, and was waiting the next day.  I noticed it didn't upgrade the
kernel; upgraded that manually, and rebooted.

So in one case, a supported upgrade (the GUI one, not the CLI one) doesn't work.  In another
case, an unsupported upgrade (even if it is only CLI -- why would there be a GUI for
unsupported stuff anyway?) worked great.

I have been using Mandriva since about 1999 (was Mandrake then) and am yet to be seriously
disappointed :-)
