How can I delete a repository link on Ubuntu ?
Is there a way to delete wrong added repository link?
I did a mistake while 'sudo add-apt-repository
'deb [arch=amd64,i386] http://wronglink trusty main'. (it was a mariadb command)
And I do not know how to delete it.
Do I edit /etc/apt/sources.list ? or ... ?
It is hard for me. Please help.
