Answer 1

• First, goto Ubuntu Software and in the menu there will be the option Ubuntu Software. Select it.
• There, you will Softwares and Updates. Select it. Check if all the official repositories (under the option Ubuntu Software) are checked. If not then check them.
• Else use the following command for installing mysql-server sudo apt install mysql-server-5.7. This should work.
