[Bug 1664725] Re: Can't link crt0-efi-x86_64.o to create an EFI application
Why does the library file crt0-efi-x86_64.o contain R_X86_64_PC32 relocation records, and not R_X86_64_PC64? ** Changed in: gnu-efi (Ubuntu) Status: New => Invalid ** Converted to question: https://answers.launchpad.net/ubuntu/+source/gnu-efi/+question/473153 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1664725 Title: Can't link crt0-efi-x86_64.o to create an EFI application To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnu-efi/+bug/1664725/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 887821] Re: "Show copy dialog" right click launcher entry doesn't work (on nautilus copy)
I too see the same thing on Ubuntu 16.04. Using the Show Copy Dialog doesn't help because it just brings up another instance of Nautilus, not the copy dialog. Alt-Tab cycles through that, not the copy dialog. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/887821 Title: "Show copy dialog" right click launcher entry doesn't work (on nautilus copy) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/887821/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
