実現したいこと
ここに実現したいことを箇条書きで書いてください。
- NextCloudをインストール直後にapps/dashboardにアクセスし、403エラーが表示されるのを直したい
前提
ubuntu 22.04.3 LTS
nginx 1.25.3
php 8.2.13
mariadb 15.1
NextCloud 28
以上の環境でNextCloudをインストールし、インストール画面は無事通りました。
続けて、アプリをインストールするか？という画面で「はい」として処理を待っていたところ、403エラー画面に遷移しました。
発生している問題・エラーメッセージ
ブラウザ上では 403 Forbidden nginx とだけ表示されています。 /var/log/nginx/error.logには directory index of "/var/www/nextcloud/apps/dashboard/" is forbidden, client: x.x.x.x, server: example.com, request: "GET /apps/dashboard/ HTTP/2.0", host: "example.com" と残っています。
試したこと
いったん/var/www/nextcloudを削除し、再インストール。
mariadbからnextcloudのデータベースを削除し、再作成。
補足情報
nginx.confは以下の通りです。

推測
以前NextCloudをインストールしたときにはアプリをインストールしなかった気がします。
それを踏まえると、そもそも/var/www/nextcloud/apps/dashboardのパーミッションに間違いがあるか、index.phpが存在しないのが問題があるような気がします。
これ以外に見直す点を思いつかないのですが、他に必要な情報はございますか？
