@jibel Your typical use case (install in BIOS mode and reboot into UEFI mode) ends typically in an error. There is no bootloader installed on /boot/efi/EFI/ubuntu and there is no boot entry in the NVRAM, which would point to shim or grub on the ESP.
The typical user has to replace grub-pc with grub-efi-* and create a boot entry in the NVRAM (/sys/firmware/efi doesn't exist, neither in the installed system, nor in the live-system). I guess, most users won't do that. They would simply reinstall in the desired mode. Another possible problem I spotted: The installer created a msdos partition table on an empty disk (which isn't a problem). The problem starts, if the user installs Windows on this disk. Windows will be installed in BIOS mode and if you change the boot mode of Ubuntu, you don't have a dualboot anymore. I didn't test it, but if the ESP is created as a logical partition, there are surely errors, if the system is booted in UEFI mode. Meanwhile, I try to find a Lubuntu dev to fix lubuntu-artwork. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873008 Title: package lubuntu-grub-theme (not installed) failed to install/upgrade: error creating symbolic link './boot/grub/themes/lubuntu-grub- theme/icons/ubuntu.png': Operation not permitted - symbolic link on vfat filesystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lubuntu-artwork/+bug/1873008/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
