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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1534374 Title: unable to upgrade to 15.04 due to libstdc++6 SRU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1534374/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
