If I get this right, there's no GRUB bootloader on Raspberry, just the U-boot itself.
It seems like something went wrong during building it from sources for the ubuntu RPi build. https://wiki.st.com/stm32mpu/wiki/How_to_configure_U-Boot_for_your_board This seems to be useful to understand the matter aswell: https://github.com/snapcore/snapd/blob/b1e9734ba1e3a397c6942b4b8dea570fdd118373/image/image_test.go#L2825 Would be nice to find some fix for this, I can test it myself before a patch is done. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1914878 Title: At boot on Pi4 with 20.04.02 i get: Failed to load '//uboot/ubuntu/boot.sel' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/u-boot/+bug/1914878/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
