mysqlを起動しようとした後、次のメッセージを受け取りました。
$ sudo systemctl start mysqld
Job for mariadb.service failed because the control process exited with error code.

何が起こっているのかよく分からない。誰でもこの問題を解決するのに役立ちますか? :永久
@tetechが提案したように、以前のバージョンのmariadbパッケージにダウングレードする必要があります。だから私は次のことを試みます:
[pi@raspi pkg]$ sudo pacman -U /var/cache/pacman/pkg/mariadb-10.4.14-1-aarch64.pkg.tar.xz
[sudo] password for pi:

しかし、それはmariadb-libs
文句を言うようで、mariadb-clients
その逆も同じです。どのようにダウングレードしますか?今、データベースを再初期化する方が簡単かもしれないと思います。
答え1
注目すべきエラーはInnoDB: Upgrade after a crash is not supported. The redo log was created with MariaDB 10.4.14.
データベースを正しく停止してからアップグレードしないようです。
10.4.14にダウングレードしてアップグレードする前に、実行したバックアップを復元または再初期化して復元する必要があります。
答え2
Manjaro Linuxの私の解決策はsudo pacman -s downgrade
次のとおりです。
downgrade mariadb-libs mariadb-clients mariadb
ダウングレードを使用すると、ダウングレードするバージョンを選択することもできます。とてもシンプルで魅力的です。
答え3
mysqlサーバーをダウングレードする方法は次のとおりです。
$ sudo pacman -U /var/cache/pacman/pkg/mariadb-clients-10.4.14-1-aarch64.pkg.tar.xz /var/cache/pacman/pkg/mariadb-libs-10.4.14-1-aarch64.pkg.tar.xz /var/cache/pacman/pkg/mariadb-10.4.14-1-aarch64.pkg.tar.xz
その後、MySqlサーバーを再び正常に起動できるようになりました。
