CUPSバナーからPDFへのエラーと「なし」バナーにもかかわらず権限が拒否されました

印刷すると、「フィルタリングに失敗しました」というメッセージが表示されます。 CUPSログによると、バナーは「なし」に設定されていますが、bannertopdfフィルタは依然として許可拒否エラー出力で失敗します。

既存のバナーファイルは誰でも読むことができますが（フルパスを含む）、バナーはありませんnone。空のファイルを作成しても何も変わりません。実際にはそのようなファイルは必要ないようです。

いくつかの背景

プリンタは、USBとネットワークを介して接続されたBrother MFC-J470DWです。ネットワーク経由で印刷ジョブを送信するときも同じ問題が発生します。

プリンタはUbuntu 19.04で動作しましたが、Ubuntu 20.04.1 Focal Fossa（LTS）にアップグレード（再インストールされていない）以降、機能しなくなりました。

このプリンタにはBrotherドライバのインストールが必要です。以前のUbuntuインストールでは、Brotherインストーラlinux-brprinter-installer-2.1.1-1を使用してインストールしました。アップグレード後、Brotherインストーラlinux-brprinter-installer-2.2.2-1を使用してください。

答え1

私にとっては、解決策は非常に簡単でしたが、CUPS設定はほとんど変更されておらず、保存する価値がありませんでした。

CUPSとプリンタに関連するパッケージを「削除」しました。もともと、

# Purge CUPS-related packages
apt purge cups cups-client cups-daemon cups-common cups-filters cups-filters-core-drivers  cups-ipp-utils  cups-pk-helper cups-ppdc cups-server-common 

# Purge Brother packages
apt purge mfcj470dwcupswrapper mfcj470dwlpr

清掃により、システム全体の構成（損傷しているように見える）がすべて削除されました。 CUPS設定が変更された場合は、まずバックアップする必要があります！ （とにかくあなたはそれらを持っています。そうです;-））

その後CUPSを再インストールしました。

apt install cups cups-client

兄弟と一緒にパック

sudo bash linux-brprinter-installer-2.2.2-1
