Dkpg error trying to install Mysql 8 on Ubuntu 18.04

I am trying to install mysql 8 on an AWS Ubuntu 18.04 instance. 
Following the instructions, I did:
wget –c https://dev.mysql.com/get/mysql-apt-config_0.8.13-1_all.deb

And the response was:
--2019-08-19 16:47:28--  http://xn--c-5gn/
Resolving xn--c-5gn (xn--c-5gn)... failed: Temporary failure in name resolution.

I then did:
sudo dpkg –i mysql-apt-config_0.8.13-1_all.deb

And the response was:
dpkg: error: need an action option

Type dpkg --help for help about installing and deinstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked [*] produce a lot of output - pipe it through 'less' or 'more' ! 

Any ideas? 

A:

Please be careful with copying commands from somewhere. 
You have typographic "–" (en dash, 0xe2 0x80 0x93) in your commands, but you should have plain minus sign "-" (hyphen-minus, 0x2d). 
You need to fix the commands to:
wget -c https://dev.mysql.com/get/mysql-apt-config_0.8.13-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb

If you are following some official guide from respectful source - then tell its author to use correct symbols. 

If you unsure about the command syntax - see manpages:

man wget locally or online 
man dpkg locally or online
