kusanagi restartに失敗する

kusanagi statusおよびkusanagi nginx --showpathの結果は以下のようになっております。

ありがとうございます。結論から申し上げると私の方の問題は解消いたしました。

systemctl restart kusanagi では解消しませんでした。その際の /var/opt/kusanagi/log/kusanagi/backend.log は以下のようになっておりました。

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: '/opt/kusanagi/nginx/sbin/nginx'

The above exception was the direct cause of the following exception:

    raise KusanagiExecutionError(
kusanagi._k10.errors.KusanagiExecutionError: '/opt/kusanagi/nginx/sbin/nginx -t -c /etc/opt/kusanagi/nginx/nginx.conf' returned 2

そこで /etc/systemd/system/multi-user.target.wants/ を確認したところリンク切れの nginx.service が確かに存在しました。

$ ls -la /etc/systemd/system/multi-user.target.wants/ | grep nginx
lrwxrwxrwx.  1 root root   37 12月 19  2023 nginx.service -> /usr/lib/systemd/system/nginx.service
lrwxrwxrwx.  1 root root   40  6月 11 10:54 nginx131.service -> /usr/lib/systemd/system/nginx131.service

こちらのシンボリックリンクを削除したところ kusanagi restart が完走するようになりました。ありがとうございました。
