Debian 11, 잘 작동하지만 이상한 시스템 오류

저는 Debian 11을 사용하고 있으며 사용자는 kvm을 사용하여 VM에서 콘솔, ssh 및 lightdm을 통해 로그인할 수 있습니다. 하지만 시스템에 오류가 발생했습니다.

서비스가 이 줄을 실행하려고 시도하는 것을 보았습니다.

grep -i exec /lib/systemd/system/[email protected]
ExecStart=/lib/systemd/systemd --user

서비스를 디버그하려고 합니다.

해결책이 있나요?

답변1

솔루션/해결 방법을 찾았습니다. systemd의 버그일 수 있습니다. grub "systemd.unified_cgroup_hierarchy=0"에서 이 명령줄을 사용하면 모든 것이 잘 작동합니다.

vim /etc/default/grub

GRUB_CMDLINE_LINUX="apparmor=1 security=apparmor systemd.unified_cgroup_hierarchy=0"

update-grub2
shutdown -r now

몇 가지 점검을 했는데 모든 것이 예상대로 작동하고 있습니다.

sudo systemctl list-units --state failed
