Saya mencoba menginstal mysql-server-5.7 di Kubuntu 16.04, tetapi saya mengalami masalah.
sudo apt install mysql-server
memberikan hasil sebagai berikut.

Dan ketika mencoba memecahkan masalah dengan menjalankan, journalctl -xe
saya mendapatkan output seperti berikut, yang tampaknya menunjukkan bahwa AppArmor memberi saya masalah.

Bagaimana saya bisa menyelesaikan masalah ini?
/var/log/mysql/error.log
. MySQL harus tetap dapat berjalan walaupun tidak dapat mengakses file / proc dan / sys di atas.
