I am getting the above erros when I try to install mysql. I tried these steps to install:

  1. sudo apt-get remove --purge mysql*
  2. sudo apt-get purge mysql*
  3. sudo apt-get autoremove
  4. sudo apt-get autoclean
  5. sudo apt-get remove dbconfig-mysql
  6. sudo apt-get dist-upgrade
  7. sudo apt-get install mysql-server

These step are from here

Is there any step I missed ?


As I see there, you have dependency problems. But, this is the first time you install mysql in that terminal?

After appears that error, introduce in your terminal: - sudo apt install -f

  • its not the first actually. It was running before as well as apache2 but after deleting my /var/log everything went nuts – guradio Sep 16 '18 at 23:54
