Alright, here is what I did. I used the default Artful sources. I started with the updated upstream ovmf version 0~20171027.76fd5a66-1.
apt-get update apt-get remove ovmf apt-get install ovmf dpkg -l ovmf | cat ovmf 0~20170911.5dfba97c-1 all UEFI firmware for 64-bit x86 virtual machines Tested package and confirmed not working. This was without the proposed repository enabled. I initially did not notice the version was the same as what you posted. Added proposed sources to /etc/apt/sources.list apt-get update apt-get remove ovmf apt-get install ovmf dpkg -l ovmf | cat ovmf 0~20170911.5dfba97c-1 all UEFI firmware for 64-bit x86 virtual machines It would seem that the package most likely moved quickly from proposed into the main repositories, however this package does not fix my issue. Installed the upstream package: dpkg -i ovmf_0-20171027.76fd5a66-1_all.deb dpkg -l ovmf | cat ovmf 0~20171027.76fd5a66-1 all UEFI firmware for 64-bit x86 virtual machines This package is confirmed working. If there is anything else I can do, let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725560 Title: OVMF UEFI firmware causes Windows 10 to not boot after upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/1725560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
