Thank you for taking the time to make this bug Alfonso! I can reproduce this in a noble-vm very easily.
$ lxc launch ubuntu:noble n-vm --vm $ lxc shell n-vm # rm /etc/ssh/sshd_config.d/60-cloudimg-settings.conf # sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config # echo "root:pass" | chpasswd # systemctl restart ssh # scp root@localhost:/sys/firmware/efi/efivars/BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c . However it's not just every file in /sys/, there are some files you can still scp. For example: # scp root@localhost:/sys/firmware/efi/runtime . You can also cp the efi variable file and then scp it fine. # cp /sys/firmware/efi/efivars/BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c ./ # scp root@localhost:/root/BootOrder-8be4df61-93ca-11d2-aa0d-00e098032b8c ./ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069305 Title: scp fails to copy files from sysfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/2069305/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
