How do I fix "Malformed entry 49 in list file /etc/apt/sources.list (Component)" [duplicate]

I have read several previous posts. But am unable to see what is wrong with my line 49 in the sources list. My line 49 reads "deb http://archive.canonical.com/bionic artner"


Solution 1:

Please add a "p" before "artner" to make it "partner".
