Below solution is to solve the rvm requirment error returns 100
If any deb command is commented in /etc/apt/sources.list than try to uncomment that command from /etc/apt/sources.list
Command is:
$sudo vi /etc/apt/sources.list
If problem is not solved than replace sources.list file with other Ubuntu's sources.list
Command is:
$mv /etc/apt/sources.list
Please make a backup before doing that
Command is:
$cp /etc/apt/sources.list sources_backup.list
Problem should solve by this time, if not than reinstall the Ubuntu.
Note: If sources.list file is corrupted than it will gives problem to install other packages.
