私はDebian 11を使用しており、ユーザーはkvmを使用してVMからコンソール、ssh、lightdmを介してログインできます。しかし、システムにエラーが発生しました。

解決策はありますか？
ベストアンサー1
解決策/解決方法を見つけました。 systemdのバグかもしれません。 grub "systemd.unified_cgroup_hierarchy=0" でこのコマンドラインを使用すると、すべてがうまく機能します。
vim /etc/default/grub
GRUB_CMDLINE_LINUX="apparmor=1 security=apparmor systemd.unified_cgroup_hierarchy=0"
update-grub2
shutdown -r now
私はいくつかの点検をしましたが、すべてが期待どおりに機能しています。
