[Bug 1534374] Re: unable to upgrade to 15.04 due to libstdc++6 SRU

[Sammael Morgenstern]

Well, I think I not alone in this. I am trying to update from 14.10 to
15.04 but it seems impossible. First I had the issue "Cannot calculate
upgrade" and after entering a bunch of lines on the terminal relating to
Xorg and other third party packages, I still unable to update.

On the step of "Calculating changes" Now, the error I get is this:

"Calculando los cambios

Calculando los cambios

Error al autenticar algunos paquetes

No ha sido posible autenticar algunos paquetes. Esto puede ser debido 
a un problema transitorio en la red. Pruebe de nuevo más tarde. Vea 
abajo una lista de los paquetes no autenticados. 

gettext 
libatomic1 
libfftw3-double3 
libfftw3-single3 
libgfortran3 
libgomp1 
libitm1 
libquadmath0 
libstdc++6 
libstdc++6:i386 
libtsan0 


the packages above mentioned "could not be authenticated"

I really would like to go ahead with the automatic upgrade. i don't want
to go through installing it from a usb or dvd.

I have upgraded from older versions till the current I have.

Bug description:
  initially had a problem with X when i installed a new Nvidia video
  card.  got that working but only one monitor was functioning (other is
  displayport).  Thought maybe upgrading to a new release might fix the
  problem.  Software update only offered 15.04, so I said ok and tried
  to upgrade.  It crashed with the info attached.  rebooted just in
  case, but still get the same problem
