In my opinion the cp command should only be executed when files exist, so it probably has to be put into some kind of "if" clause (or needs an "ignore-if-empty" option). ** Affects: acpi-override (Ubuntu) Importance: Undecided Status: New ** Summary changed: - acpi-override-initramfs makes update-initramsfs fail as long as /var/lib/acpi-override/* does not exist + acpi-override-initramfs makes update-initramsfs fail as long as /var/lib/acpi-override/ is empty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892035 Title: acpi-override-initramfs makes update-initramfs fail when /var/lib /acpi-override/ is empty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi-override/+bug/1892035/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
