#14 - I'm honestly not sure; I expected dependent packages to complain about the downgrade, but they didn't.
(Note: It's likely that all relevant architectures must be installed with the same dpkg command. Maybe it'll work if you use --force- depends?) This worked for me: $ sudo dpkg -i gcc-4.9-base_4.9.2-10ubuntu13_amd64.deb gcc-4.9-base_4.9.2-10ubuntu13_i386.deb $ sudo do-release-upgrade -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
