To be more clear (some times I'm not very confident about my English): TFTP server = proxyDHCP server = where shimx64.efi is. UEFI and BIOS and iPXE and all clients, use the proxyDHCP server as the TFTP server.
Shimx64.efi on the other hand, tries to download grubx64.efi from the real DHCP server, which usually isn't a TFTP server when proxyDHCP is used, and fails. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813541 Title: Shim uses wrong TFTP server IP in proxyDHCP mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1813541/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
