Tidak dapat menginstal atau menghapus MySQL

Jadi hari ini saya menginstal MariaDB sehingga saya bisa masuk melalui phpmyadmin, ternyata tidak berhasil jadi saya menghapusnya, mencoba lagi seperti empat kali dan saya gagal. Memutuskan untuk pergi dengan Server MySQL sebagai gantinya. Saya tidak bisa menginstalnya setelah menghapus MariaDB.

Inilah yang saya coba lakukan dan hasilnya:

shavit@dedi:~$ sudo apt-get install mysql-server

Saya seorang pemula dengan segala sesuatu yang berhubungan dengan Linux dan khususnya Ubuntu. Adakah yang bisa membantu dan membantu saya? Sangat dihargai!

Saya pikir fakta bahwa Anda telah menginstal MariaDB menyebabkan masalah ini. Konfigurasi yang diatur MariaDB tidak persis cocok dengan MySQL vanilla. Jika Anda membersihkan semua konfigurasi lama dan mengatur semuanya dari awal, itu akan berhasil. Perhatikan bahwa ini akan menghapus DB Anda saat ini! Cadangkan data penting apa pun.

Coba jalankan perintah berikut untuk mengatur ulang dan membersihkan semua hal terkait MySQL:

sudo apt purge mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7 mysql-server-core-5.7 mysql-server

Setelah ini selesai, jalankan di bawah ini untuk memperbarui sistem Anda dan "bersihkan" cache paket Anda.

sudo apt update && sudo apt dist-upgrade && sudo apt autoremove && sudo apt -f install

Kemudian, coba instal ulang Server MySQL:

sudo apt install mysql-server

Kesalahan ini dapat terjadi ketika Anda menginstal mariadb-serversebelumnya mysql-server. Untuk mengatasi kesalahan ini, Anda harus menghapus direktori /var/lib/mysql*dan /etc/mysql*menghapus semua file konfigurasi dan dependensi, sebelum mencoba menginstal MySQL lagi.

sudo apt purge mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7 mysql-server-core-5.7 mysql-server
sudo apt update && sudo apt dist-upgrade && sudo apt autoremove && sudo apt -f install
sudo apt install mysql-server
