If it isn't apt's job, then I suggest that it's aptdaemon's, not USC's. You should get the same error whether you try to install the package from USC, from the Dash, or (if it ends up in a PPA or third-party archive somehow) from Software Updater.
If so, reassign to me and I'll spec the error presentation in <https://wiki.ubuntu.com/SoftwarePackageOperations#installing-or- updating>. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1171931 Title: Installing multiarch debs can uninstall native arch packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1171931/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
