Sau khi nâng cấp lên Ubuntu 16.04, tôi nhận thấy mysql đang có những lỗi không đáng có. Tin tưởng, đó là một thiết lập bị hỏng, tôi đã thử chạy một cuộc thanh trừng mysql. Điều đó dường như không xóa tất cả mọi thứ, vì vậy tôi đã cố gắng tự làm điều đó:
sudo rm -r /etc/mysql
sudo rm -r /usr/share/mysql-workbench
sudo rm -r /usr/share/mysql
sudo rm -r /usr/share/mysql-common
Đây là một sai lầm. Đừng bao giờ thử làm điều này. Bây giờ mysql thậm chí sẽ không cài đặt chính xác. Tôi đã thử cài đặt lại các phụ thuộc:
sudo apt-get install --reinstall $(apt-cache depends mysql-server | grep -Po 'Depends:\s+\K[^ ]+$' | tr '\n' ' ' )
Và bản thân các gói:
sudo apt install mysql-workbench mysql-server --reinstall
Nhưng tôi nhận được tất cả các loại lỗi khó hiểu, chẳng hạn như:
sudo apt-get install --reinstall mysql-server

Là apt không thể phục hồi từ một phần cài đặt? Tôi có phải cài đặt lại hệ điều hành không ??
sudo apt-get install --reinstall mysql
chưa?
