Noticed something interesting. the entry for rescue kernel is not updated in /boot/loader/entries -rw-r--r--. 1 root root 392 Nov 30 2019 189711f94e78436d9618b891a8fce70e-0-rescue.conf Has this in it, but is version 32 not 30 any longer?? title Fedora (0-rescue-189711f94e78436d9618b891a8fce70e) 30 (Workstation Edition) version 0-rescue-189711f94e78436d9618b891a8fce70e linux /vmlinuz-0-rescue-189711f94e78436d9618b891a8fce70e initrd /initramfs-0-rescue-189711f94e78436d9618b891a8fce70e.img options $kernelopts id fedora-0-0-rescue-189711f94e78436d9618b891a8fce70e grub_users $grub_users grub_arg --unrestricted grub_class kernel Don't know if this is with the new-kernel-pkg message that it can't find a theme. Strange didn't find that in that file, so message must come from somewhere else. Tried moving it, to see if it would be recreated if it was missing, but neither building a new rescue kernel or running grub2-mkconfig created a new one. So, put back the old one. Seems the names are the same. Didn't try booting it.. > _______________________________________________ > users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx > Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx +------------------------------------------------------------+ Michael D.
