And the longer a password becomes the closer it get's to be recognized as certificate. ;-)

Don't get me wrong, adding more possible values per character by adding numbers and uppercase letters etc. also makes it harder to calculate a password, of course. But each additonal character in length easily outperforms additional variations per character. Mathematical example: 26^2 = 676 (that's lowercase a-z, 2 characters long), 104^2 = 10,816 (that's lowercase, uppercase, numbers, special characters), 26^3 = 17,567 (that's lowercase a-z, 3 characters long).

IMHO there are two attac vectors to passwords: a) someone knowing/stealing your password and b) someone guessing your password. To protect you against variant a) you use choose a secure way to generate, store and enter your password. To protect you against variant b) you limit password entry rate and then just hide behind a mathematical barrier that's stronger than current CPU power. That's it. The longer the password, the harder to calculate.

I agree with most of the answer, exept 6. Password. Please stop spreading the false recommendation that uppercase/lowercase letters, numbers and symbols will make a password more secure. It's all about the length. I simply use passwords 24+ characters long. See Hard to guess – easy to remember: xkcd on Password Strength.

Here I am. Let me know, if you stil need help.

I was asked to creating a chat with you instead of using comments for it.

User ID and Group ID for system services are normally around 100-150. 1010 is wrong. it should something like 107 or 110 or 117 etc. Now to the new error: Ok. Let's change the symbolic links again … || rm /etc/mysql/mysql.cnf || rm /etc/alternatives/my.cnf || cp /etc/mysql/my.cnf /etc/mysql/mysql.cnf || ln -s /etc/mysql/mysql.cnf /etc/alternatives/my.cnf || now try again.

Now it's getting a bit more complex. I've added more instructions to my answer to help you. But be careful editing those two files mentioned!

What error does the install command show this time?
