I am completely new to ubuntu.
I am trying to do UBUNTU BOOT Repair ( ubuntu 12.04.3 lts precise)
While I'm doing so I'm facing the below error.
" E: Type 'n' is not known on line 3 in source list /etc/apt/sources.list.d/yannubuntu-boot-repair-precise.list.
E: The list of sources could not be read "
I have tried giving " cat/etc/apt/sources.list.d/yannubuntu-boot-repair-precise.list "
It displayed an error as "NO such file or directory"
Please suggest me what to do further
