printadmin
グループを作成して自分を追加しました
Sudo groupadd printadmin
Sudo usermod -a -G printadmin ma
この投稿 ごとに、lp
グループについても同じことを行いました。
その後、再起動しますが、管理インターフェイスの[プリンターの追加]をクリックすると(localhost:631
)、以前と同じ「プリンタを追加できません:禁止」エラーが発生します。ログファイル/var/log/cups/error_log
にはこれが含まれています
E [16/Sep/2017:11:34:23 -0500] [Client 24] Returning HTTP Forbidden for CUPS-Get-Devices (no URI) from localhost
E [16/Sep/2017:11:34:23 -0500] [CGI] CUPS-Get-Devices request failed with status 401: Forbidden
新しいことは何も教えてくれません。何が悪いのですか?
私の(Fedora)cups 2.1.3のcupsd.conf
のmanページには、
以前はcupsd.confファイルで許可されていたファイル、ディレクトリ、ユーザー設定ディレクティブが、代わりにcups-files.conf(5)ファイルに保存されるようになりました
したがって、SystemGroup printadmin
行はおそらく/etc/cups/cups-files.conf
に移動する必要があります
