Fedora 29のdnfデータベースディスクイメージフォーマットエラー

私はこれを次の場所にクロスポストしました。Ask.fedora.orgなぜなら、これまたはその向こうにFedoraのユーザーベースが大きいのか、まだわからないからです。

このエラーのため、数日間更新をインストールできませんでした。

問題を解決するには、これらのコマンドを実行する必要があることを知ってみましたが、問題は解決されませんでした。

  • dnf clean all
  • dnf makecache
  • rpm --buildddb

存在するFedoraに提案を依頼してくださいdnfは回復できず、SQLiteデータベースは手動で回復する必要があります。

与えられたコマンドを実行してみました。

sqlite3 history-<date>.sqlite ".dump" | sqlite3 history-<new date>.db && rm history-<date>.sqlite

これは/var/lib/dnf/history/history-2015-10-25.sqliteうまくいきません。これを行うと/var/lib/dnf/history.sqlite新しいエラーが発生します。

この問題をさらに詳しく見ると、sqlite3 .dump次のようになります。

/var/lib/dnf# sqlite3 history.sqlite .dump 
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
/**** ERROR: (10) disk I/O error *****/
ROLLBACK; -- due to errors

history.sqliteところがそこにコピー/tmpして.dump実行すると、そんなに安く見えるデータベースが出てきます。 GUIで開くとsqlitemanうまくいきます。データベース自体は問題ないようです。

データベースを別の場所の新しいファイルにダンプして再コピーすると、次のような結果が表示されます。

SELinuxタグも復元しましたが、何も変更されませんでした。

-rw-r--r--. 1 root root unconfined_u:object_r:rpm_var_lib_t:s0 29M 26. Jan 13:52 history.sqlite

このファイルはルートでも読み取ることができます。

/v/l/dnf# head -c 1000 history.sqlite 
SQLite format 3@  ,�,.,P��⏎

Fedora 29の状況は何で、回復できますか？

ベストアンサー1

システムを再起動した後、このダンプを再試行しました。 SELinuxタグのリカバリを調整する必要があるかもしれません。これでアップデートが再び機能しているようです。
