On ZFS setup, boot/grub/ uses the EFI system partition to store GRUB configuration so, it's always readable by grub on boot. This partition is of type vfat and this filesystem type doesn't support symbolic links.
The problem with lubuntu grub theme is that a file used for the theme is a symbolic link, so dpkg cannot extract it to the VFAT partition ls -l src/boot/grub/themes/lubuntu-grub-theme/icons/ubuntu.png lrwxrwxrwx 1 u u 11 avril 3 10:10 src/boot/grub/themes/lubuntu-grub-theme/icons/ubuntu.png -> lubuntu.png A solution at the packaging level is to create a copy instead of using a symbolic link. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
