不能再在新的 Debian 服务器上安装 mysql 8（尚未配置包 mysql-community-server。）

直到几周前，我才能够在全新的 Debian Buster 安装上安装 mysql server 8。

sudo apt update
export DEBIAN_FRONTEND=noninteractive
sudo apt full-upgrade -y
sudo apt autoremove -y

sudo apt install gnupg -y
wget -c https://dev.mysql.com/get/mysql-apt-config_0.8.17-1_all.deb
sudo -E dpkg -i mysql-apt-config_0.8.17-1_all.deb
sudo apt update
sudo -E apt install -y mysql-server

但是某些东西似乎已经发生了变化，Debian Buster 10.9或者mysql-apt-config_0.8.17-1_all.deb导致了下面的错误。

错误：

update-alternatives: using /var/lib/mecab/dic/ipadic-utf8 to provide /var/lib/mecab/dic/debian (mecab-dictionary) in auto mode

  Package mysql-community-server is not configured yet.

 mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

我完全被卡住了，因为我不明白错误消息。因为配置应该在安装后发生，如下所示：

sudo systemctl start mysql.service
sudo systemctl enable mysql.service
SECURE_MYSQL=$(expect -c "
set timeout 10
spawn sudo mysql_secure_installation
expect \"Would you like to setup VALIDATE PASSWORD plugin?\"
send \"n\r\"
expect \"New password:\"
send \"$DB_ROOT_PASSWORD\r\"
expect \"Re-enter new password:\"
send \"$DB_ROOT_PASSWORD\r\"
expect \"Remove anonymous users?\"
send \"y\r\"
expect \"Disallow root login remotely?\"
send \"y\r\"
expect \"Remove test database and access to it?\"
send \"y\r\"
expect \"Reload privilege tables now?\"
send \"y\r\"
expect eof
")
echo "$SECURE_MYSQL"

请问我错过了什么？

更新：

根据评论，这是我调查的结果：
